Dear Mother

All I want to say is, "It is NOT your fault. It will NEVER be your fault. What happened to you is inexcusable. No one should ever be put through anything like that. I don't know the extent of your abuse but just know none of this is your fault. If you were so young you can't blame yourself for not understanding. Your parents were there for protection and love and instead they tormented you. Please, NEVER EVER, EVER blame yourself for this. You couldn't have saved your sister either. Just know, the pain you feel will only fester if you continue to burden yourself for someone else's wrong doings. You will heal in time if you love yourself and forgive. It'll take much time but you can do it. Stay strong, Mem."

Heya, Memsie.

First off, I sense that this goes really deep, and I hope the things you say in here aren't really true. No parent should ever feel like their child is a burden, no matter how wild they are. (And if that really is true that they felt that way, you should know that your family here on YWS will never think of you as such. We love you.)

Next, I'm going to address your letter in itself. I caught feelings when reading it, because it reminded me a little of my own life. There isn't much that I can say that hasn't already been said, but I'm going to stress the point that you need commas. And as for the main message of the letter, you don't sound so sincere. Sort of like a teen who is being forced into writing a letter of apology.
"Biological" shouldn't be capitalized.
"The took your daughter..." I'm just going to point this out, instead of correcting you.
Later on in your letter, you sound more sorry about fighting with your mom.
I think you have it just how you want it, but if I could, I would suggest a separate paragraph dedicated to praising your mother, telling her how hard she's had it, and that you don't mean or want to make it harder for her, because causing her more stress is the last thing you want. Or don't, because it's YOUR work. Do what you want with it.

Still, I want to repeat that commas are important, but don't over do it, because you don't want comma splices.

And I really did love this, because it's easy to read, and very relatable for some of your readers. It's always nice to read something that confirms that I'm not alone in how I feel.
Thank you for writing.
As always, keep reading, writing, and reviewing!

Hey there Mem! Luata here to do a review! I really, really like what you have done here. I was looking off to the side of the screen and I saw you had many different letters written to various people. I have something like this to, just not published and with your permission, I would like to swipe your idea of a collection of letters. Please! I won't though, if you would prefer so otherwise.

Anyway, onto the actual review part of this. Because this letter is so personal, I am not going to grammar check it, to me that just seems .. . . out of place. I just wanted to say that i really appreciate this piece because it is so easily clicks with many people who have gone through the same things that you have gone through.

I'm sorry if this review isn't very helpful, I just think that this is very brave of you.

Hi, there! I'm here to review your letter if that's okay. If you weren't looking for a review at the moment, then just ignore this. You may want some input at a later time though, so here we go
I could tell this came from the deepest, darkest parts of your heart. I applaud you for having the courage to put this out there. When we write emotionally, we tend to stumble over our words or mess up our grammar here and there. I know I do it all the time! Here are just a few suggestions in case you were planning on creating a story out of these letters, or simply editing them at some point in time:

You need a comma after "Dear Mother."

"I wasn't mad at you, even when I say I am I'm not really mad." You also need a comma here, "...even when I say I am, I'm not really mad."

"Mom I'm so sorry and I mean it." You need a comma after "Mom" here.

"For some reason I just never got the reason." I would change this to "For some reason, I never caught on," or "For some reason, I never got it."

"Im trying to be the woman you want me to be now though, and maybe we can mend our relationship." I don't think the "though" is necessary, and we can reword this a bit. Perhaps something like this: "I'm trying to be the woman you want me to be, the woman you always knew I had the potential to become. Maybe there's a change we can mend our relationship, maybe there's a change we can love each other again." I think there needs to be more raw emotion, more of a punch for effect. Just some suggestions

"It wasn't your fault that my Biological father and his whore of a wife abused me to the point I will never be the same girl again." You don't need to capitalize "biological" here. I might also change the end to "...to the point where I will never be the same girl I once used to be," or "...to the point where I will never be the same," even suffices. You could still leave this and it'd be fine, but you do need some sort of conjunction between "point" and "I" or else the sentence doesn't make sense grammatically.

"I'm so sorry mom and I love you" You need a comma and punctuation here: "I'm so sorry mom, and I love you."

Overall, this is an emotionally pulling piece. It cuts deep and being so personal really opens up doors for you creatively! Don't take any of my suggestions to heart I'm simply giving you a little advice on how I would revise this letter if you are thinking about editing this.
I think letters leave you with the opportunity to create great stories, and it'd be a rewarding and amazing process to compile the letters you have written and create a story with all of them.
Let me know if you'd like me to review any more of your letters or any work for that matter. Your emotion shines through here, and you have great potential as a writer!
