Hi AnIslandNeverCries, it is really good that you've got a T and it sounds like you're making progress with her in managing to open up to her. Is there anything in particular stopping you from telling her more of what's going on for you though? Or anything you think would help in you doing that?
As for the periods in between seeing her, does she set you any homework/tasks/challenges/coping resources? If not maybe it's worth talking to her about.
It sounds like you're feeling really alone in this between sessions, which has to be hard. But do you think you could "let it out" in a journal, then maybe share this with your T? As your time with her is relatively short this may give her a bit more insight into some of the thoughts/feelings you might find it hard to discuss.
And perhaps try a help/crisisline, to give you a bit more support?? while things are this hard for you. It can take time and support to begin moving more past the way you're feeling but that's not to say it can't be done, just try to share as much as you can and try to reach out for the support that is out there (and here!!

)
