Dear Angel,
I think your instincts are right, especially with the symptoms of hallucinations, you do need extra help. Do you have a primary Dr for your Bipolar Disorder? When I had some of these symptoms my Dr strongly urged me to have a psych eval, and possibly be hospitalized for a few days to straighten out my medication and symptoms. He stressed it was dangerous to try to do it on my own. I was in Acute Mania, which is serious.
I don't say that to scare you or cause you more anxiety, but there is help out there. At this point, it would be best if it's professional help.
Family means well, but they don't always understand the severity of the condition when it's in an acute stage like this.
I'm not a medical professional, just passing on my own experience. You shouldn't have to suffer through this.
Very best of luck. Please take care of yourself FIRST, otherwise you won't be able to take care of other responsibilities.
