I'm a massive hypochondriac and I think I have leukemia. It all started Tuesday morning where I woke up and I thought my lips were numb and so I started googling and I stumbled upon a website that said cancer was one of the causes. I got so terrified that I started feeling really anxious. This continued into Tuesday evening where I went out to get some food but my old knee injury was inflamed and I struggled to walk with pain in my left knee for a couple seconds. I got nervous when I got to my dorm and I did even more googling and I found out that leukemia causes joint pain. And what do you know, I got even more nervous! All of a sudden, I felt my legs getting weak and my shins started to have a slight sharp pain. To make matters worse, my old chest injury got inflamed and I started to feel discomfort. I looked up more symptoms of leukemia and I found out that night sweats and bruises were listed. I started to get nervous again and kept checking myself for bruises and then when I to take a nap, I woke up sweating. I was also scared that I would lose my appetite the next day since that's another leukemia symptom and since Wednesday, I haven't had an appetite. I pretty much been forcing myself to eat and there was one point where I almost threw up. Then on Thrusday, a dark mark on my skin that I've had on my arm for awhile has started to burn anytime I touch it or lay on my mattress. Now it's friday, and my mattress left a red line on my arm that started as an imprint and now I feel the same small burning sensation when I lay on my bed. I’m not sure if these are bruises or not. Someone please help me because I truly don't know what to do.
