I'm so glad you've been brave enough to tell someone and you're planning on phoning CMHT on Monday. It's really hard when everything feels weird and wrong and you can't quite work out what's happening.
I think you need some expert help about the medicines too, as maybe you're getting side effects which are making you worse, or maybe you're taking the wrong dose for you, or maybe you need to carry on to get the benefit - so difficult to know especially when it's happening to you.
Here's my story about medicines - dont read if you're tired and knackered as its a bit long and I don't want to make you drained!
I was on some amazing 'wonder drug' which was supposed to stop nerve damage pain as well as being an anti-depressant. It wasn't lisenced in the UK and I really wish I hadn't asked about it as it turns out its not a good one at all. It made the pain massively worse, have me heart palpitations and high anxiety and made me suicidal. I definitely wasn't thinking properly and I had no idea what to do or what was wrong.
When I came off them (v slowly and gently though), my brain cleared and it was like I'd been in hell those months. But i didnt just go cold turkey as that woyld have been a bit unsafe. So I am a bit worried about you doing that without help 
Then I tried another med and it helped this time... So it wasn't just coming off the medication that helped, it was having an expert working with me to get the drugs right.
I really hope you can bear it to reach out and get some of that help and advice. It's really good to get a professional who knows all about medicines to help you find the right combination and dosages for you.
Good luck and lots of nice thoughts wafting in your direction
