New glasses causing serious issues?

I've had my new glasses for roughly a week. I hate them! Instantly, when I put them on things were blurry. I told the girl right then I couldn't see too well. But of course I got the "it's a new script and it takes time to get used to" speech. After an hour of use that same day, I got a killer headache and so dizzy I had to take them off and put my old ones back on. I started getting bad anxiety-sweating, and crying because I was frustrated that I couldn't see well. I went back to the place I had the exam and they checked the prescription to make sure it matched the lens, it did. And again, I got told I have to give them time. So the following morning I woke up thinking I was going to wear them and after a couple hours they came off. I noticed things were blurry mostly out the right eye when I covered the left. I called back my doctor for a prescription recheck and yesterday he said he was getting a different prescription read than before. He said he may use my old script just make it a little stronger. But after further investigation at my eyes he said I had extreme dry eye which could be why my new prescription isn't working out so well. He told me to try eye drops for a week and if things still suck to come back and he'd adjust the prescription. So i've been wearing my new glasses for 8 hours now and I still get a massive headache within minutes after they are on, my eyes feel strained and I immediately feel exhausted. The floor looks uneven and objects look swerved.
Added (1). … This is all mostly with the right lens still. I have noticed when I am outside I can see things bright/clear as day but inside everything is blurry/fuzzy and weird. While on the computer the letters are blending together same while reading a book or magazine. While looking around the room many objects have a "fishbowl" effect as it's called. I seriously don't feel like I can last a whole week. I'd rather go blind with no glasses than wear these right now.
Added (2). So idk if it's the lens that's the issue. It's a new lens for me nikon polycarb sv. It's supposed to be a better lens but everything is so distorted, even though their supposed to cause less distortion. It's a rectangular lens with thick plastic sides. The doctor said these ones may just be too strong for me and I may be better off with a plain poly carb lens like what's in my old frame. So idk, I just know I can't take it much anymore.
