Loneliness

Loneliness comes in a wave of tears,
With broken hopes, and isolated fears,
where sadness treads, far quite unseen,
and no one cares for your well- being,
it hits like sorrow, guilt, and pain,
and drives some people very insane.
Yes, that's loneliness, and now it comes,
hurt some others, pass by some.

I didn't think it was brilliant, but I certainly liked it.

Short, but powerful. Not astounding, but very nice rhyming and beautiful word choice.
There was only one thing that bothered me.

it hits like sorrow, guilt, and pain,
and drives some people very insane.

Firstly, I didn't like the word 'like' here. You could just say 'it hits with sorrow, guilt and pain' and it would flow more and I didn't like your 2nd line. It didn't fit with the mood of the rest of the poem.

where sadness treads, far quite unseen,
and no one cares for your well- being,

I loved these lines, beautiful.

Good job, keep writing. I look forward to reading more of your work...

Simple. That's all I can say.
It was simple.
Hopefully your next work will expand upon ideas and be a bit longer.
