I think and feel like I'm a big loser!

Hey guys, usually I don't share anything about my life with anyone, or else in any social media. I'm 22, living a loser's life. I don't have any special talent, was not even good at studies (below average). Last year i finished my Bachelors degree in Computer Applications with 1 backlog in 5th semester, which I wrote re-exam in this January. I was doing cybersecurity course from three months, and it's coming to end in next week. I still not know much, I feel like I'm living mediocre and loser's life. Not soo good looking, with receding hairline, haven't maintained good physique, not too good with money, have family problems, no supportive family members, it may feel like I'm exaggerating but, I don't even friends. When i try to change, I can't keep doing anything consistently. I sometimes think I'm just acting like living a good life, and be better person after my breakup last year. As a guy with no such societal pressure on me I feel like a big LOSER.
