I'm not going to tell my girlfriend I am in therapy
Why would you hide going to therapy from your girlfriend?
I don't want her to judge me
It can be embarrassing to admit to our loved ones that we need therapy, but it's important that you let your girlfriend know what's going on with you. If she doesn't know that you're in therapy, then she won't be able to support you emotionally.
You'll see, I'll tell her.
Okay great. She will probably be a great source of support for you on your therapy journey.
