Sorry to hear that. The comment below does give good advice, presuming you're not an actual goblin and that you're somewhere around average height, you can put odds in your favor by staying fit, well dressed and well groomed. Lack of hair, get hair implants, etc. Get braces or dental work if needed. The result is superficial but the confidence gains will be real and you'll feel better either way. After that I would advise signing up to a rock climbing gym or something and getting out to meet girls in real life, in case your dating app profile still doesn't help by then. I think most of all, let go of your hate towards yourself/your parents/your appearance. This kind of bitterness consumes you after a while and it will show in your personality.
