Things don’t make sense anymore/unpredictable mindsets

I don’t know what’s happening to me! Everything has become so confusing. My mind is all over the place and I have no idea how to deal with it.

I was at work today and I felt as if I couldn’t talk (literally), everything I did say came out so disorganised, muddled and I stuttered my words (which has never been an issue in the past) sometimes 4 times in a row. The thing is i’m actually aware that my mind is breaking down but I don’t know what to do to stop it. was sent home because I was seemingly depressed. I just don’t feel like myself anymore, I feel so useless and stupid.

Almost a year ago, I came off medication. I started to become more aware of the mood switches I was having and so I started to keep a mood diary. It was becoming increasingly clear that I had a mood disorder of some kind, and a lot of my symptoms have led me to believe I could be suffering from bipolar (I was thought to have this), although another part of me doesn’t believe it.

A few weeks back, I started suffering from a mixture of different emotions all at once and to the extremes. Recently, my thoughts have slowed and I feel as though i’m becoming more and more depressed as the days go by. I can no longer function properly and I feel as though i’m unable to do anything. Socially I’ve become more awkward to the point where i feel as if I can’t be close with anyone at the moment. I’ve also been getting into very mild psychotic like states that are very hard to explain. Everything becomes so disorganised in my head that I feel as though i’m suffering from brain damage. It gets worse as the days go by but i’m reluctant to seek help because I don’t want to be misdiagnosed again.

I had been on the wrong medication for years and I suffered extreme brain dysfunction during it and yet they didn’t do anything about it. Now i’m away from all of that i’m hoping to get better. If this is a severe depressive episode of bipolar, how can I best cope with this? If this doesn’t sound like bipolar, what could this be? Are these symptoms common with patients with depression or am I going mad?

I would talk to a psychiatrist. They can diagnose you properly. Then get a 2nd opinion without telling them what the 1st doc thinks if you want reassurance.
If you do have bipolar you'll probably need medication. In my experience the most helpful is a mood stabilizer like Lithium or Lamictal and an anti-psychotic. When I'm stressed, anxious, or have insomnia I also take Klonopin.
