Remove Becker Nevus. Please help me.

I have big black dark patch on right shoulder, this we know as baker navus. I know this is a harmless mole/birthmark but visually it's not. Usually other people didn't ask questions about it and if they did, they usually told me that it is not a big deal. However it became a big deal for me. I started to avoid scenes at public when I had to take of my shirt (for example at the gym) and I also evaded places like the beach or public baths. Even when I was alone at home, I didn't like to walk around without my shirt. At this point I realized that the actually harmless BN did constrain/influence my life in a psychological way. It is easy for other people to tell you that it is not a big deal, because they don't have to live with it . Seriously i am very very disappointed and frustrated with this, it is killing me some times. Please help me to get rid of it. I will be very very grateful. PLEASE HELP ME.
