I am getting help but the self harm cuts on my thighs show when I wear my swimsuit shorts so how do i cover them up?

There isn't much you can do besides use some make up to try and cover them or try one of the products (found at CVS, Walgreens, Walmart, etc.) that state they can diminish the look of scars.

I used to cut as well. I still have scars all over my left arm. I haven't tried the scar diminishing products out there, but probably should.
