My unusual situation

im 22 years old now. i live alone and im down and drepressed all the time. ive never had a relationship ever. no girl, no love, no kiss, no nothing. ive never even had a real female friend. i even avoid watching movies because the love scenes gives me anxieties.
its not that im ugly. in fact im very not ugly. everytime i go out some girls gives me looks and others stare. i have a very ruggish manly look, near perfect body and handsome face. but i never approch these woman who stare at me. in fact ive never approached a woman in my entire life like that. i wouldnt know what to do and i would probably mak a big fool of myself. i got no charm and game at all and i certainly cant talk in a flirty way. every girl at the gym seems to be in love with me, but i cant even smile at them. its like a big mental blockage. but it also feels that if i would date a girl in a csaual way, i would lose my shot at true love.
i dont tolerate people calling me gay but somethimes i tell people who's wondering that i simply dont need love. this is a big lie and i need it more than ever. im just so lonely. i dont go to college and i dont work, all i do is go to the gym and occasionally meet friends.
what should i do? what CAN i do? i cant even remember the last time i was happy. how can i stop being so lonely?

i know this all might sound weird but its the truth and i seriously need some good advice
