If you're over 23 and still khhv, just give up on women and move on.
No amount of self-improvement will improve your face structure or increase your height. Personality is useless, being fit doesn't matter if you're ugly.
You were never meant to have a girlfriend in this hypergamous dating market. The privilege of experiencing pure youth love is reserved for the top 40% of men and you're clearly not part of it.
Crush any little hope you may still have and accept your fate. Because only then you will be free from this rat race, and you will be able to enjoy your life to the fullest. Wasting your youth chasing after an impossible dream will only leave you bitter and frustrated.
