Dear Li1,
I can identify with everythig you say. I have bi-polar disorder, and when I am very depressed I don't want to see anyone or do anything, I just want to curl up in a ball on my bed and not move.It is difficult when you have things you have to do (Christmas preparations for example) because you force yourself to keep going and end up totally exhausted. You don't feel up to interacting with other people, and as you say you shut yourself away.
All you can do is go into survival mode. Rid your life of eveything which is not absolutely necessary, and try to get plenty of rest.I don't know whether or not you have told your family and friendsabout your illness- I suppose it depends on how you think they will take it. In the long run, it is a very positive thing to do.I have been "out" for decades, and now I find my family and friends incredibly supportive. It is up to you to judge when is a good time to tell them. But being supported by family and friends is incredibly enpowering.
You don't mention whether you are under the are of a health care professional (GP, counsellor, psychologist, psychiatrist). You don't have to deal with all this on your own, you know. It might be a big step to make that first call to the GP but there are so many people out there who can help you. It is probably too late now to get an appointment before Christmas, but I hope after Christmas you will reach out and get some professional help. You will kick yourself for not having done it years ago.
Don't feel you have to put on a big performace over Christmas. If someone asks you whether you are working just say "I am between jobs at the moment" and close the conversation at that. Ask other people questions about themselves - everyone likes talking a about himself, and that takes the pressure off you.
I really feel for you, especially at this awkward time of year.Make yourself a New Year resolution to get professional help next year.It can be your Christmas present to yourself.
I have had bi-polar disorder for 47 years,an d have somehow managed to whether the ups and downs.I wouldn't be able to do it without my great psychiatrist, I I hope you will also find someone to help you.
Best wishes
Ellu
