T.F.
Go to the dermatologist and get to the root of the issue.
Don't be ashamed... you need help and they are there to help, not judge you.
I wouldn't be putting anything on my skin until I saw a Dr. and knew what was going on. As far scar relief, when and if you manage to get the cut well, vitamin E oil is great for scars. Use it regularly and it will help.
Good luck.
