I'm going to dump all of my mental problems on my friend.
Why do you want to dump all your problems on your friend?
Because he doesn't have problems of his own.
While it is normal to share with your friends and help each other with problems, it is not good to overwhelm them with everything. They will want time apart from you when it gets to be too much.
Maybe you have a point. I think I sometimes resent the fact that I seem to have so many more problems than my friends do.
I like seeing your self-awareness. It can be the foundation of moving on to more constructive coping processes.
