You do have bipolar disorder, and you did inherit it both genetically and from learning poor coping skills. I think the first thing you could benefit from is a good therapist to help you deal with people more effectively. I think you are also dealing with anxiety and depression because you have bipolar disorder, and you would benefit from a mood stabilizer and some antianxiety meds...it will be okay--it is just time to get some assistance in managing your life so you can feel better.
Bipolar disorder does run in families. It's important to not ignore how you are feeling- it sounds like these emotions are all the sudden coming up, I'd recommend getting to a doctor as soon as you can to talk things out and get the ball rolling on what your next steps are.
Let us know how you are doing!
It sounds like the symptoms are related to that diagnosis but don't label yourself. There can be other factors affecting your symptoms. Set up some support on the medical and emotional aspect to get a confirmation.
It helps to keep a record of your patterns in mood and sleep as well as outside factors like situations, sleep and daily habits that have trigerred a mood. This way you are able to see if something coincides with another. Also it helps when you can show the doc and he or she can see your perspective in a clearer way. The trackers in this site have helped a lot in my experience. You can also print out reports to show doc. I hope there will be an app. This has been the most throrough site and use it as opposed to an app.
Hope you can get something worked out for ya. :)
