I know you are hurting. I too had a female T that decided she couldn't handle me anymore and I need to find another. Trust me...it will get better. in hind sight, XT was CBT and I needed Psychotherapy.
Best thing to do, is pick yourself up and dust yourself off and get back on that bike. I immediately found a new T, after interviewing several, he helped me process the first T ditching me. Maybe you are just out of the realm of her area of expertise... that's what it sounds like she is saying... even though it may not feel that way. It doesn't seem personal, she is looking out for your best interest.
