Did something happen like an accident or something that changed how you are able to live now?
When I first moved to my farm here 4 years ago, there was an auto accident in front of my house. I was the first person at the accident & had to call for the paramedics & try to care for the kids until they got there. The boy that was driving was lucky to end up living after they were finally able to cut him out of the car.....but they didn't know about the Traumatic Brain Injury until after he was later transported to the university hospital in the city.....couldn't air lift him at the time because of the weather. The thing was that with the Brain Injury, he had to learn how to do everything over again from the point of being a child & will never be able to function past about a 3rd grade level.
Sometimes we just have to accept what happens in our life & live the best life we possibly can given the situation we are in. Know it's not easy when our life changes & we aren't able to live the way we were able to live before.....but we can still have a wonderful life & learn to be happy with who we are in the NOW.
Hope your therapy can help you work through some of these difficult things that you are trying to deal with in life......your T should be working with you on coping skills to help you when you are struggling with the issues you seem to constantly be struggling with now.....along with the concept of accepting the things that aren't possible to change & focus working on those things that can be changed.
