For the past 2 months, i've been having difficulties. It started with this numbness at the back of my head/brain, then moved on to pressure on different spots on and off. Now it's like either a constant headache, or a heavy head, or the pressure thing, it's different every day. I feel sometimes like i'm not even present, people will be having a conversation and i have trouble concentrating. it affects my vision too in a way, i don't know how to explain it, it's almost like i need glasses, but the images are clear, i just can't focus. i need to really try, and even then it feels different somehow. I'm constantly tired. I get to school and I'm beat already. It could be a number of things, and it could be something very easy to fix, but i don't know what to do and this affects me constantly every day. It's rare that I don't feel these symptoms. I just want to feel normal again.

can anyone help?

p.s. I posted this in the teenage section because I'm 17 years old and was having trouble finding another category that was more fit to it.
