I need some genuine advice. This is going to be quite lengthy but here goes. I'm a 24 year old white guy and i just feel like shit most of the time, i don't like myself and i don't feel like that's ever going to change. I'm fat and have been most of my life, i have very limited work history (two temporary, month or so jobs). I have obsolete qualifications and zero confidence to the point where i feel like i literally can't do anything right. I have zero income and have literally been living off of the money i earned from the temporary work, which runs out next month. I have to pay my mother rent, and a gym membership i pay for, which i try so hard to motivate myself to go to, but often don't go to. I sit indoors all day, have next to no friends, and most of the time i feel like avoiding people so they don't have the misfortune of having me in their lives. I now seem to get angry at the littlest things. I basically just feel completely useless and like no matter what i do, nothing will change, because any time i try, it goes wrong, or i get rejected. I can't remember the last time i truly felt happy, and i just don't feel like i'm good at anything. Most of the time i just don't want to think about it so i just play video games to avoid it.
So i just.. want some advice to break out of this seemingly endless spiral of despair. I need a job because i need to pay rent but anytime i look at any job application, i rule myself out of it immediately, thinking i can't do any of it, and i'm terrified they'll ring me up if i do apply because i don't know what to say. I have applied for a few but they never get back to me.
