Annoyed at my family

My mum and sister keep trying to get me to see a counselor. It's really annoying I've told them over and over again that I don't want to see one. My sister goes to see one every week.

The reason they want me to go is because I was sexually abused/Inappropriately touched for the past 12 years. While also getting mentally abused.

I've already learned to cope with it in my own way, which isn't the best way as I keep everything locked up inside. I just don't like talking to people about how I feel and stuff like that never have, mostly because no one was every around to listen or they didn't care.
