I've posted to you on the other thread too, but wanted to catch you here as well about
the mania, tape weight and anorexia stuff.
Please please please don't start undoing all the work you did to get yourself to the "post-anorexic" stage -- that takes some doing: you know I know how much!!! Once this cycle starts (and I think we can agree that mentally it has, even if the physical is just across a -- very fine -- line) you are the last person who's going to be able to assess accurately what's ok and what's not in terms of your weight and body shape. Even people without anorexia frequently add a couple of inches in what they "see", but anorexics and bulimics are notorious for having a very distorted body image. Is there a helpline or group you could contact to help you with this? -- In my experience they are normally run by people with personal experience of the disorder, which means that they should be able to really understand. You definitely need to address this, and the sooner the better. It *never* brings happiness.
My anorexia was much like yours -- trying to starve myself and then finally eating and inducing vomitting. In fact for ages I thought I was bulimic because I didn't understand that anorexics often purge too. For years I thought I was a failed anorexic -- that I just didn't have the will-power to be anorexic so I was bulimic... . Hm, I realise the screwy-ness of my thinking now. The reality is that of *course* you can't keep starving yourself: it's not that you don't have the power to do so, it's that human beings were not designed to run on air.
This is "feeding" (pardon the pun) your bipolar and vice-versa at the moment, and I don't see any happy ending unless you *get help*!! Please please do this: you're too important not to take every care of yourself that you can. Not sleeping just adds to my sense that the mania is taking over -- it's a common symptom of the manic phase. Many people can't see this when they're in it: it's not a failing, but it is something that we can see and that you can use us to help you measure at the moment. Do use what we say to help yourself.
