I had a T tell me I must not have really wanted to die right after I attempted suicide because I "didn't pick a deadly enough method." I heard that as, "Dumbass. You can't even kill yourself the right way. You should have done it THIS WAY."

Not to mention it completely invalidated how horrible and hopeless I was feeling. That was a big one, but I am also extremely sensitive and get offended easily by little comments any T makes here and there.
What your T said to you would have bothered me too. The way you described it it just sounds like it came across really harshly. I probably would have cried.
