I'm sorry he said those things to you. I had a somewhat similar moment with a friend, who said something along the lines of that I am smart enough to figure things out on my own and I don't need therapy. I talked to my therapist about what I thought of this and came up with some good insights for myself.

They don't understand what you are going through, I don't share those "dark moments" with my friend because to me it is sad. She doesn't know that I missed a lot of work because I just could not get myself out of bed or was feeling panicked and paranoid about what the world would bring that day....people who don't suffer don't "get it" and you have to accept that and realize that what they are saying may be a product of an experience they had with themselves or with someone else. Just focus on yourself and getting help through this. I told my therapist that I thought seeking treatment was the smart thing to do because I could not cope with my reactions to life on my own, but I am learning.

I hope you can figure things out and move on from what your uncle said. I feel for ya.

Take Care
