Listen, Sam. You're being too hard on yourself. You can't do this to yourself buddy. You made a perfectly reasonable decision which has pros and cons. And you're focusing on the cons.
Look, here's your worst-case scenario: The hair transplant looks like crap, and you can't stand your hair. There are still good options. There always are.
There are wigs you can get which blend in with your existing hair and you can slowly add more of your own hair to them. To the outside eye people won't really notice anything. Even on close inspection they look totally natural. Wigs these days are very good. You can do anything with them, exercise, sweat, pull on them and they won't come off.
Personally, this is my back-up plan. I recently had a HT and if I go to norwood 7 I will do this. The reason I do HT because I want to see if it works.
However, I take propecia and that is keeping my hairline in place. If you try the big 3, finasteride, minoxidil and ketoconazole, there is a good chance you can keep what you have and prevent going to norwood 7.
Don't forget the gym and exercise these will help with your feelings. At 9 months post-op of course you can sweat. What do you mean it doesn't feel normal?
Do you have any photos you'd like to share?
