Extreme burning when I pee? It is so bad I cry, please help.?

I'm not sure if I have a yeast infection or a urinary tract infection. Its a little over half way down the and hurts if I press on it, even when I'm just walking around. But the real issue is when I go to urinate because it hurts tremendously. It started today, and its so horrific I'm terrified to go. I've looked up home remedies, and most of the tips are to drink lots of water- which will make me have to go to the bathroom ( but that will make it unbearably painful!) Please help- my mother is not being any help at all. she gave me this cream but that isn't helping too much and I took a bath with baking soda and it didn't help either. please help me- it is so painful.
