Hi miranda,
Welcome to HW. Being bipolar is so hard. The best advice I can give you is to have professional support, a pdoc, and a therapist. I was in a bipolar support group and it helped me tremendously. I have to get my sleep (your seroquel should be helping you with that...I'm assuming you take it at bedtime) and I have to keep stresses away. I took Lorazepam for a long time, just recently switched to Clonazepam--these definitely help with the anxiety.
Anyway, being a memeber of this forum is also very helpful in releasing stressors and getting information. We all understand you here. It's definitely one single day at a time...
