Hey there
See a doctor, ask for help. Its simple.
Yes BP is genetic (manic depression is a very old term and I cannot believe its still sued but some doctors persist in it..) in linkage and its more prevalent in families BUT that does not mean you are bipolar.
I hate to say this but BP can be genetically caused.It's a chemical imbalance in the brain. There are so many sides to BP,see your family doctor asap, I'm not sure what a cpn is? psych nurse? I would still suggest seeing a psychiatrist as well.
It's important to catch this before it gets worse. Try to keep as productive as you can, even if it's just getting out of bed, showering and brushing your teeth, that's a start.
Keep in touch, and let us know how you're doing.
when you're hiding read, read, read
this site is very helpful
hope you are better soon, its a long ride
