Hi Tmac, I am sorry that you are in such distress right now. My explanation for depression is that it is from not learning how to express your feelings mostly and from learning some other maladaptive things. Of course you have to be susceptible to depression but it takes the environment to trigger it. Therapy is so important for learning what we need to do to feel better and for expressing all of those repressed feelings. Can you ask your T why she feels this way?
