Tried to open up but bf said I need help

I tried to open up to my boyfriend that sometimes I'm having a hard time understanding him and it bothers me a lot whenever I feel jealous, overthink, and sensitive. I have been keeping it to myself because I don't want to confront him with it because I don't want to be toxic so I always try to calm down and evaluate my feelings alone.

After opening up to him he said it is evident that I need psychological help and that I should admit that I am not well and do therapy.

I know that and I've been trying to find a psychologist. While I agree with what he said, a part of me just says that this guy is a bit tough.
