I'm going to add some more things I have done in the past when I was having a really hard time: get my diary and phone and arrange little dates/meet-ups with friends. At one point I was a member of a really nice health centre too, and I could go there for a swim which relaxed me. Go for little walks, with different routes planned. Call the samaritans: I don't usually do this, but I did once or twice when T was away and I felt really bad. It didn't help in the long-term, but it did help in the moment to get through a bit more time and it generally helped me calm down a little bit. I have some favourite CDs to listen to, and I would put them out ready for myself. One is a talking CD, I always find it helpful.
I'm putting all the things I can think of and hope it might be useful! Another thing is that you can give yourself a lot of positive affirmation during this time:for example, so far you have managed one week without T, and even though it's been so hard, you have managed. Perhaps you can keep note of all the things you have done to cope to share with T afterwards, and think how proud T can be and how proud you will be - I think even though it's hard, it can be very good for our self esteem to realise the things we CAN cope with. I've had that experience recently.
This may all be not helpful and if so please ignore and go with whatever helps you! I am just putting down all I can think of, because I feel for you, because two months really is a long time.
