I think your T's reply is right in line with most T's responses to contact outside of the therapy time. When contact between sessions is possible, it is pretty limited because therapy needs to take place face to face and in the therapy session. Contact between sessions is more about keeping the connection, so we can hold on to that until we can be face to face again. An email or phone call just to connect is reassuring and they do understand that, and how important it is. I can imagine your T also understands that it is hard to have so many things happen that keep you and T from being able to meet for so long and would be fine with a call or email about you missing her and missing having regular sessions with her.
You have a lot going on, many worries and responsibilities. I hope you can get back to regular sessions with your T to help with all of the stress that you feel in so many ways.
