Urinary tract infection?

25 year old male- For a bit over 24 hours now it feels like someone kicked me in the stomach almost. And theres a lot of pressure in my bladder it seems. It feels constantly like I have to pee even when I don't. It doesn't hurt when I pee though and I heard that was another symptom of it. It hurts when I breathe in and out and I could barely sleep last night, it was horrible. I tried pepto in case it was just my stomach and it didn't help at all. What do I do? I've heard cranberry juice helps urinary tract infections? Any other advice in case thats what it is? I just lost my job and don't have insurance either so going to a doctor isn't happening. So at home remedies will have to do. It's worked for 25 years anyways, no need to start seeing a doctor for every little thing now. Ha. Thanks in advance!
