One of the most important thing you can do for yourself is learn to love and accept yourself for who you are. A lot of self hate and disgust for one's self and body is purely mental and in the mind.
A lot of it is enemy curses, some of it may come from negative interactions from people in your life, or could be from deficiencies of planets in your chart that may need some work. Blitz and Korpi and the others already have given you some good advice in regards to all of this.
Changing your perspective to one that is more positive about yourself may not be easy at first but using positive affirmations about yourself daily can help you gain a better outlook on yourself. Telling yourself that you are beautiful and worthy, complimenting yourself and highlighting your best features. Wearing clothing that makes you look and feel good. Working out and eating well, just taking it easy and replacing negative thoughts with positivity, and implementing small changes like this will lead to good habits and a happier more positive life and feel of yourself.
If you were to go for plastic surgery with the negative mindset you have of yourself it would solve nothing, you may keep finding flaws in yourself and getting more and more surgery until you've completely ruined your body. Plastic surgery is not a solution but changing your mindset is!
Good luck and don't hesitate to reach out for more support if needed.
