I know, we know, how you're feeling. When I was younger, this nearly drove me to suicide. Everything you've done so far, I've done too.. sometimes things look like they're getting better, then you get impatient, throw something new into the mix, and it ruins everything you had going...
I'm 32 now. I've had this since I was 16. I know that doesn't help with how you're feeling, I just want you to know I understand.
Try to think of it this way... how often when you're talking to someone do you think of their lips? Obviously you might, because of your condition, but if you didn't have it, you probably would never even consider them except maybe ''oh those are nice full lips'', or ''those lips are paper-thin'', etc..
This isn't like a giant mole in the center of your face; as long as you keep it controlled as best you can, no one will even notice.
I've seen enough derms that I'm just over it. I'm going to see an internal medicine doctor in March.. I know this is an infection. For instance, when I work out hard, my lips swell in certain areas. I've looked into that, and it's a sign of an infection, most likely yeast.
Guys here have been talking about it being a yeast infection for a while.. I'm with that. One of the first derms I saw said it was a yeast infection and gave me Nystatin cream for it.
Still not cured. I'm trying to clean out my insides now in hopes that that will change this.
Anyway, don't let this consume you. It is HARD to not let it, but you are more than you f***ed up lips, alright?
A LOT of people have their own problems. Some people have herpes, man, and that shit is for life.
