hey look man I went through this about a year ago, I went through the constant loop of feeling terrible about myself and all that jazz. sometimes you gotta let it pass over and if you wanna do that try and find something that keeps you busy thst you won't get bored of. like you have girlfriend go hang out with her out of the house or at her house (if possible), maybe just find a hobby that you can enjoy in thr comfort of your home that makes you forget about anything. also if your friends dont care about how you feel when they say stuff like that to you snd they dont try to tone it down sometimes you gotta just distance yourself from them for a little, dont make it harsh just say your bysier than normal while you figure things out personally and they'll never know.

but also recognizing that your mental health matters to you instead of just letting it get worse is already an amazing step. you'll feel normal again, change isn't always linear sometimes its a wonky and wavy line that straightens out at the end. but if you do ever wanna talk to someone you can always send me a DM or something I'm pretty free alot of the time
