(((aries)))can you see your t more often till you get out of this bad slump? i know for me that helped a lot when i could see no value in myself and was so severely depressed. i could so relate to the feelings in your original post. i used to feel the same way all the time. i had no hope. today that has changed considerably. it was by using my therapy and in my case meds too that helped me regain my life back. i hope the same can happen to you too.
since you felt like the therapy session helped, if even for a short while, if you can arrange it, i would see if you can go more often for now. (hope you can).
in the meantime know that we see you as a person of value even when you don't. we are here for you. i am glad you posted about what's going on with you. it helps us to try to help you. we're all here for each other.
