Hi and welcome to SR. So very sorry about your parents. I can't even begin to imagine the pain of that tragedy. I do know that when I stopped drinking I had to really even learn how to feel emotions and get through them. It was like I was a baby and never fully matured. I still am learning and I imagine the learning process will continue.
Good for you for seeing a therapist AND consulting with your doctor. You certainly are taking the right steps. Just wanted to pop on and say welcome to this very helpful site. I would think you will get a lot out of it.
