I'm really scared to take my antibiotic😭😭😭

I ended up in the ER last night with a UTI and was prescribed the antibiotic Ceftin 500mg 2x a day oral suspension (liquid, not pill). I heard the taste is awful, and that it can cause diarrhea, nausea, depression, anxiety and constant/hard to control vomiting. Most of these reviews came from a website called askpatient where 90% of the reviews were awful. I'm deathly afraid of throwing up, and really don't want to take anything that can possibly put me at risk of it, but at the same time I don't want this infection anymore. My anxiety is already as and I don't need it getting worse. I take probiotics daily and I'll be upping my probiotic dosage when I start the antibiotics tomorrow morning but I'm still totally freaking out. I've been taking 2x my normal dosage of probiotics today as well. I have emetrol and dramamine (anti nausea drugs) on hand just in case but I'm seriously freaking out about taking this med, I really don't want to. I've only ever taken amoxicillin and had no side effects but this is a different class of antibiotic therefore I could react very differently. This antibiotic, Ceftin, is a lot stronger than amoxicillin, apparently. There's also a chance I could end up being allergic, although I'm not a very allergy-prone person. I'm also not vomit prone (haven't in years, but that doesn't mean I can't with this drug). Have any of you guys ever taken it?? What should I do? Help :(
