A Complete Circle With No Help Out

I used to have bulimia, but Ive managed to stop purging. However, Im still binge eating quite a lot. It gets worse when Im having a depressive episode, and then when I see how big I am and how I cant lose weight from exercising because of how much Im eating, I enter another episode and it becomes a cycle.

I havent seen my therapist or doctors in months because I cant drive myself and my friend who used to drive me got their car given away by their dad while at college. My parents said they would start taking me, but then they took it back, which caused my biggest episode to date and now Im over 250lbs. I just want to stop but I either eat all day or dont eat at all.
