ER or No?

So I have a uti as far as I know. I went to a walk in clinic and they gave me some antibiotics because I had a lot of blood in my urine and also sent it off to be tested. Well every sense I have been feeling extremely tired, feeling off, also having hallucinations when waking up I didn’t have these before feeling bad. The blood hasn’t been as much today and the burning but the hallucinations were back again tonight and now I’m up afraid to go to sleep. Also having extreme back pain?
