Depression, anxiety, bi-polar thinking.

I am getting weird dreams since last 2 weeks. I tried free writing that day and came up with this weird idea thats stuck in my brain. I feel like my life has become a game and I cant win it. I get anxious talking to people thinking they might judge me. I need consultancy to get over this anxiety coz I have an overthinking mind and all useless thoughts are consistently hitting my brain making me go out of focus. I have exam in few weeks and I scored good last time but now I am not able to study since last 4 days because of overthinking. I also get hallucinations and fear when I am in my house at night thinking someone is watching me. I dont believe in ghosts thats why I am trying to see a hypnotherapist to find whats wrong with my mind
