please pay attention to me

i'm not very happy with my body so i want to know if i could get anything out of fitness for strength/appearance or if i should just give up and focus solely on cardio for health over everything else. my main problem is that i have the same shoulder size as a teenage girl.
my greatest desire is for somebody to tell me to either give up or keep trying. i'll listen if the opinion seems well informed. i'm 23 years old, a khhv, haven't talked to a woman my age in a casual setting in almost a decade, and starting to recognize that i'm way too old to feel insecure about my body. it's wasting my life. i want to know if trying to become involved in that sphere (sex, relationships) is even worth it or if i should abstain. the latter hasn't been bad so far. i've gone around 2 weeks without masturbating and my erections are being less frequent as time passes because frankly any thought of sex makes me want to kill myself
