Unsure of dating

There is this absolute wonderful, caring, funny guy, totally not my type but im passed that stage with looks. I have been single for a hella time, had loads of confidence until my knee injury an now with a stick until it fully heals, so im left with no confidence and full of anxiety 😣 this man really is into me but im full of insecurities now. He has asked me out on a date, and now im thinking should i? Ugh, iv gained weight, look hideous with a crutch, vulnerable, not like i can leave hella quick if all goes wrong 😂. I dont know whether to give this date a chance, as it is just a date nothing more. Just cant help if anything developed into more, cant do normal couple stuff, get on knees if you know, you know 😂😔

Any advice ladies?
