A lot of organisations accept clothes and other belongings as donation for those in need.

I am in no position to tell yourself what to do or not with your life. I know that telling you "things will get better" is just a nice way to try to get you to endure it further. As good or bad as it is, people are mostly clueless on how to handle such situations but try to be supportive. The only things I can do is be here to listen if you need someone to talk to.
