I’m so scared right now

About two months ago I realized that I was peeing more than usual and I took a test only for it to come up negative. I looked up other reasons other than pregnancy and came up with some frightening discoveries. Today I noticed a really bad headache and and my ears having pressure in it. I’ve also had a nosebleed when my headache and the ear pressure started to go away and my right leg is in pain but I’ve been in bed since I got home. I’m really scared right now and I can’t afford a hospital and I just had to cancel my insurance because I don’t have money to pay for it. I was just wondering if anybody else has experienced this?
