Struggling alone with PCOS and being shunned by my family

No one else understands my struggles. Not even my parents or siblings. Everyone just says to eat less, move more. I wish that was possible. I walk 10k steps a day for work. I eat one meal a day as well cause people say intermittent fasting is good. I’m already tired from work. I don’t have energy to do things. I feel like I might have sleep apnea as well. Being told that I snore and waking up with a dry throat. For a while I keep thinking I got diabetes but no. Did blood work every 6 months. And it’s not diabetes. I don’t feel awake with 8 hours of sleep, I only feel rested on 10+ hours.

Anyways my cousin is getting married in June. Only wanted to attend her wedding because I never been to a wedding before. A few years back a childhood friend got married and I wasn’t invited. Even then my mom said it was due to my weight. Although we are not friends anymore I still feel depressed for a couple of weeks. Recently my mom called and said it sounds like my aunt doesn’t want me to go to her daughter’s wedding. Yeah cause of my weight. This stupid weight. Can’t make friends in school. Can’t get a friend cause no guy would like someone that looks like this. Everyone is attracted to good looking people. Initial attraction is all based on looks. Being accepted in society also all depends on looks.

Recently, I finally felt at peace with work. Cause all co workers are strangers. You just work together occasionally. So no one cares about your looks. Was finally feeling good about myself, working on school and doing my job. At this point I am just living day to day with work being the only social interaction I have. No friends outside of work. No family to talk to, cause they always go on and on about my weight. Hate my life. None of my family believe me when I tell them that I don’t eat a lot. They just won’t believe it. Was finally at peace living on my own, working at self improvement for school and work. Now I just feel my life is shit. People my age are already married and having kids. I’m still alone, working. No savings. No money. And school is never ending cause I’m not smart. Why can’t I pass my classes? Having to repeat so many years I just want to scream. No family. No friends. No career. No money. That’s where I am. Even trying online chat services is stupid. All pay to use. I just want to talk to someone. I just want to scream.
