I finally decided to ask for help on here about DP

It started back in the middle of April and it's getting worse. I feel like I'm not here, like I don't exist; a fog in front of me. Yet, when I'm driving to work, I seem very alert and have had no accidents and my vision seems ok even though I do wear glasses. This seems to have started from high amounts of stress from my job. I work in a warehouse that stores medical records (probably about 400,000 boxes or more) and on a daily basis, I have to drive a picker to get up to the high areas and file charts and I always get scared that it's going to tip over or I'll fall to my death, despite me being attached to a safety harness. Also, there are tons of dark sections where you need a headlamp and I'll be in the dark for 10 mins filing charts and when I come out, I feel like I'm not all there. On top of that, sometimes snakes get inside and I'm deathly afraid of them. I feel like all of this has triggered some kind of defense mechanism and that's what's led me to start having this.

When I'm talking to people, I start to get this weird feeling that I'm having an out of body experience or the people I'm talking to are gone. I barely get any sleep and wondering if that could be part of my problem (I get about 5 hours of sleep per night). I exercise somewhat regularly and eat good. I don't smoke or drink. I've had all of these weird thoughts that I'm about to be "unplugged from the Matrix" and wake up or that I'm actually dead. My doctor wanted to put me on Zoloft, but I heard bad things about that pill. Blood work came back ok and was wondering what tips anyone can give me. I feel like this is going to be a lifelong experience.
