Summer time vs scars?

I have self harm and some scars that aren’t self inflicted.

I hate it. I feel I can’t wear T-shirts, or shorts I feel judged and embarrassed.

I definitely won’t be able to go swimming or the in hot tub.

I have and still self harm so I have scars from that. But I also have a scar on my tummy from an operation.

How do you deal with it? Help me out.
