I don't plan on sticking around anymore so I'm just wondering what the easiest way of getting rid of all my stuff is
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.
Wishing for something nice to come your way, hope you do stick around
You could give away the stuff to others, depending on where you live put it up on some marketplace. Maybe like eBay. Will also depend on whether you just want to get rid of it or earn something back from the sale.
Take a long walk through a beautiful forest, take in all the greenery and fresh air and maybe reconsider. Life is precious. You can always sell all your stuff and just leave. Ever wanted to live as a backpacker? Just go wherever you want and the road takes you.
I have my out planned. Don't care what happens to whatever stuff I leave behind.
