Has anyone experienced severe withdrawals from their medication either by changing meds or coming off of them completely? If so, how did you deal with it?

I'm currently stuck on Venlafaxine because of this and it's starting to really affect my health. I was supposed to transition completely onto Trazadone but because of the withdrawals I was unable to and now I'm taking an unhealthy (and kinda dangerous) mix of the two.

I stopped taking the Venlafaxine for around 5 days before I wasn't able to deal with it anymore. I was so dizzy and nauseous that I was unable to move from my bed. I felt like I had the flu and it caused me to become extremely frustrated and angry and I ended up with very vivid thoughts of suicide and self-harm. I'm actually so terrified of the thought of going through it again that I nearly lashed out at my psychiatrist who told me that "it was just something that I had to suck up and deal with."

Honestly all I want is to be off of this damn medication but I can't see a safe way in which I'll be able to and I really don't want to end up back in hospital.

So if you have any advice on how I might be able to get through this, please let me know. I know that'll I'll probably have to "just deal with it" but I'm desperate for other options.
