Right, it's not going to last forever because bipolar is a cycle, right? You know that you will come out of this current low. It's a matter of taking it one day at a time. Tomorrow you can reassess the situation. Every day you can reassess the situation and do what you feel capable of doing on that particular day. You've managed two weeks already - that's great and a real achievement in itself. It's okay to have a bad day now. Maybe now is the time to go to see the doctor. You've already managed 2 weeks without seeing him, so now you can go and feel good that you did well for two weeks. Setting manageable goals short-term is a lot more effective than trying to go for a huge long-term goal like "I'm going to do this totally alone for a long time with no help". Those goals just drain you after a while. Set yourself lots of short term goals instead and feel good about the ones you achieve and try not to beat yourself up over the ones you can't manage yet.
