Therapy

So today I walked out on my session with my psychologist. It's a long story but for a long time now I've felt that I'm just taking up the time of those people that make up my treatment team and that I've barely gotten anywhere...it's been bought to my attention and I don't know, some things were said today and he wanted to see me tomorrow but by the time I consented....well I haven't heard anything back so maybe its too late. Do I just walk away? I don't know. What is the point in taking up so much space if things are not going to improve because *I* am incapable of improving them? I've been given an amazing team of people that are intelligent and caring and I feel that I"m just throwing it all away...not intentionally, I DO do what is asked of me and I'm incredibly honest about everything...but I'm still pathetic and not improving. But so far I've stuck with them not because I think its right or helpful but because I'm too scared to stop seeing them and live with the pain and hurt on my own... I'm scared that if I changed my mind and asked to go back that in all likelihood they'd be full and it would be an impossibility, besides why would they take me back if I'm the one that screwed up and left too early. I already know that there is no one else to see, no one else to try, so there is no point looking. I'm just confused and scared and I want things to change, so why does change seem so impossible?
