Could what I'm about to describe have been a hypomanic episode? I've been wondering about this since it happened about a year ago. It's all a bit of a blur so I might have forgotten a few things or got a few things wrong chronologically

Leading up to it I was low in mood for a good few months and that resulted in everything being to much for me and me drinking a bottle of Vodka and passing out by a motorway. It was a few days after that that what I think could be a hypomanic episode happened.

It was one of the worst experiences of my life. I didn't sleep for about three days, maybe longer, I can't quite remember. It lasted about a week and ended in me going to the hospital and being referred to a crisis resolution team.

The thing is, I didn't have elevated mood which most people describe when talking about mania/hypomania. Instead I was scared, extremely irritable, had bizarre thoughts that my mum was going to kill herself, that I had a brain tumor, that she was going to die in a car crash etc., my anxiety was higher than ever. I couldn't concentrate on anything, my thoughts were racing and my mum couldn't understand what I was talking about when I spoke with her. I was constantly pacing about in a panic. I started seeing things, like walls moving, things out of the corner of my eye, and a few times I heard voices. It built up so much that I ended up phoning the crisis resolution team one day and demanded that I see someone about my situation soon because I couldn't get through the next few days without doing so.

About an hour after I phoned the crisis team I saw a psychiatrist and she put me on Valium, which calmed me down, zoloft and zopiclone which helped me sleep, and that sorted me out for the most part.

I had a similar experience some months later (october, I think). I didn't sleep again for two or three days and I was seeing things again and heard a voice. This freaked me out and I went to the hospital again and saw the same psychiatrist and am now on Olanzapine (antipsychotic) as well as antidepressants, and my mood is now stable.

Does this sound like bipolar or maybe Cyclothymia? Could this have been a hypomanic episode?
