I have a headache

I have no friends (why? No clue ask everyone that doesnt respond to me or message me first. I thought I was good at making friends but clearly not). I overthink just about everything. I am jealous of my boyfriend and his big group of friends. I get jealous when he chooses to hang out with them over me. I dont get it because I dont have any friends. I lay in bed almost every day and I try to sleep a majority of the day away. I have depression or what I believe it to be ( i have never been diagnosed with anything as I've never talked to someone professional). I have no motivation to do anything at all. I dont think I'm good enough. I'm very self aware about everything I'm doing. I feel like everyone is always judging me. Especially my boyfriends mom. I dont think she likes me, she is a very rude person and really hard to be around and any "jokes" she says kills any confidence I have in myself. Like I said. I dont think I'm good enough. Sometimes the overthinking is too much for me to handle, I wish I could just stop thinking about all the negatives but I cant and no one I know seems to understand that I can't. Everything is giving me a headache and my brain wont shut up. Somedays I'm okay but most days I'm not. I overthink about things almost everyday. Even the little stuff. I just hurt and I want a break. I've never talked about this before and it just makes me want to cry and honestly typing this makes me hurt more.
