it's sad to hear that you are planning to leave soon. i am sorry for the way life has treated you, and i wish things could've gone different for you. it may be too late for me to set up a 1-1 talk with you about things, and even though i advise against proceeding, it's only right i give you answers to what you've asked for.
the person above me is correct about pawning.
since your possessions are of no use to you now, i don't see a reason to keep anything. you can make easy money by selling stuff online with Mercari for anything that's pretty niche, Poshmark for brands, eBay for pretty much anything, or as suggested previously, just go over to a pawn shop and see what they can offer. if FB marketplace is popular in your area, you can also use that to your advantage.
pawning & selling, whichever works easiest for you.
you can also flip stuff. take a used item bought from any thrift shop, fix it up, and resell it on a marketplace for profit. maybe you can find inspiration or a drive to keep going from that :)
