Suffering Bad Case of PPPd

I have a very bad case of PPPD well at least that’s what they are saying. I’m so dizzy and can’t take light. My left eye coverges and my ears full and ringing. I get no breaks and basically bedridden. My vision very blurry and nothing seems real. I can’t function. Please tell me this is something else. I hace a ton of floaters and haven’t showered I days. I’m seriously contemplating ending it all. They are switching me from Pristiq to Zoloft starting tonight. Can’t even watch TV. What is this? Is PPPD really this bad? I can’t even walk I’m so dizzy. Everything tilts forward. I don’t want to live like this anymore.
