I would suggest using something like Google Scholar to get solid results. Google Scholar only searches available scientific papers, meaning they're a little more credible than the average google search.
A writer is a world trapped in a person— Victor Hugo
Ink is blood. Paper is bandages. The wounded press books to their heart to know they're not alone.
Google Scholar is certainly an excellent source, however some of the articles might be filled with jargons you don't understand. Hence, I also recommend you check out Quora, it's an intellectual base forum covering a wide base of questions. You can check the user's answers with articles you find, on top of that you can also get autobiographical experiences like this link I found when I typed in your question.
Of course, there are always books.
