Just got my first glasses, I feel they are not right

Got them today, I was recently diagnosed with nearsighted astigmatism and got a prescription from a doctor. I put them on and something felt off, at first I thought I'm going to get used to it but I tried them on and off at home and realised I don't see sharp or clear, still looks like astigmatism.

And Yes the vision changes, but without glasses my right eye sees well at near sight, with them it's worse, my left eye sees properly at near sight with the glasses, and bad at long sight. So if I look with both of them it looks off, almost worse in my opinion. I'm worried the prescription is wrong and I have to do it all again and pay for it again. I'm also feel dizzy and kind of want to vomit, but the vision is worse.

I'm actually at the verge of tears, I thought I would feel amazed but I'm disappointed instead, I feel terrible and have no idea what to do.
