Hello everyone

i have question about dealing with my insecurities.

I have developed physical condition where my muscles get weak faster than normal peopleand it's progressive. so right now i cannot lift "heavy" stuff and my legs get tired after walking for about 3~4 hours and i also limp when i walk. i used to think dating was over for me. and part of me still thinks that way. i mean i never heard any girls saying "I love dating guy with physical disability" say no girls ever. fyi this condtion does not hinder my sexual performance haha i give my girl orgasm at least 3 times per week and i know she loves it cuz she basically becomes animal when we are in bed haha

anyway the problm is that my gf somes worries alot about my conditoin. i mean i understand cuz she sees it whenever we meet. and when i see her worrying about me, i honest feel really bad.. it makes me feel like i am not good enough for her and i get inscure about it. she said she worries cuz she cares for me which i understand but i start feel bad that i am not as healthy as normal people and have more fun with her. if there something i can do to cure this condtion then i would no matter what it takes but unfortunately there are no cures yet. i still hit the gym every day and try to clean...

how do you deal with your inscurities like that?
