It's not normal for me to jump on someone like that. This touched a sore spot in me back when I was still struggling with my identity. I agree that there is a time for tough love, but this is not that time. This is a time to let him vent and see that he is allowed to have those feelings. Give him time and he will work though them just as I did and many others here. If he pushes his feelings onto others, that's when it's time for tough love. That's someone thriving on misery. I don't see this as the case.
I think he has come to the right place, let's give him room to grow where it's safer to do so and where others can understand.
