Maybe it would be useful to consult with another T, just for one or two sessions, about the situation you are in with T1 - just wondering if an outside person and perspective would be helpful.

I totally get what you mean, about feeling that it truly is a life threatening situation. I feel like that too, and I've had episodes like the ones you describe, of feeling totally abandoned.

For me, it's not 100% fixed, but it's much much better - the episodes happen much less frequently (there was a time before I came to therapy when this happened almost daily, certainly several times per week) and now I would say it's a few times per year. It does feel really terrible and life threatening when it happens but also the emotion comes down more quickly. So I guess for me what Lolagrace says really resonates - that this can be about getting to a place where it is manageable, rather than completely fixed. My T said something similar as well- he said we could think of it as something like living with asthma. You're never going to not have the condition, but it can (hopefully!) be brought under control so that it's not having a big negative impact on day to day life.
