Unfortunately I cannot tell you how to stop feeling like this but if you find the solution - please let me know as I have exactly the same problem... But what I realized is that actually after some time it is a bit better and I have to keep myself busy - working more, going out more, meeting others etc. So that I do not have so much time to think about it... I thought that having sessions twice a week would help - it didn't, it was even worse because I didn't have enough time to go back to the routine between sessions... Now my T went to the conference and I didn't see her already for 10 days and it is much better...
