I'm glad your T called back and that you feel better as a result. Not second guessing leaning on her sounds like a good plan - if you're already feeling down, you don't really need additional things to worry about.

When I went through a particularly dark time last year, I found myself leaning on my therapist a lot more. I don't ever call her, but I probably called her 1-2 times per week during that period. She reassured me that it wasn't too much, and that she knew that when I was feeling better I would feel less of a need to contact her. I don't know that I believed her at the time (the tunnel of suicidal thoughts can really do that to you), but she was right.
