I'm 19, I was constantly compared to others. What should I do?translated

Reader question:

Good afternoon. I'm 19 and completely depressed. All my life I was “not good enough”, I was constantly compared to other children, their successes, devaluing mine. I didn’t notice before, it was enough for me to ask for forgiveness for nothing, it turns out... It turned into guilt that I drag with me. I'm in my second year, studying to become a doctor. The most offensive thing is that I still hear comparisons with people who couldn’t even get into a university, especially in my specialty. I feel like a ballast for everyone, not good enough, smart enough, beautiful, thin enough. I don’t drink or smoke, I don’t walk in the alley, I study, I try my best. In relationships, I was compared to others. You see, I don’t have as long hair as he likes, or I don’t have a manicure like the other girl. I endured it, and then I exploded, and now I have so much resentment, pain, and anger at everyone who said that to me. Okay guy, but when close people are a stab in the back. I don’t love myself, my body, I consider myself the ugliest and I begin to consider myself insufficient. I don’t see the point in psychology, I always thought that the best psychologist is faith.

But our hands gave up so much that everything was lost, even faith. I don’t see justice in life, why do people like me...
