health anxiety (headaches)

hey guys I’m 13 (lol you probably know by now cause I post on here all the time but this forum and the people on it really help so thank you!!) my dizziness has gotten better and I have been drinking way more water. Unfortunately I still have headaches. I’m not so convinced I have a brain tumor anymore but still need some reassurance. (Also sometimes I bump into things lol like a lot but I’m not off balanced and feel like so idk if I should worry about that) anyways back to the headaches, they are very short pressure on my head that last for idk sometimes 2 seconds all the way to maybe 30? Idk if this is just “head pain” I also will get it randomly it doesn’t have a set time where I get it more but I do notice I get them a lot more at night. They are very mild and feel like pressure and I don’t know if this is tension headaches. What do you guys think? Much love to everyone because I know how hard it can be. My whole summer was wasted because I thought I had a horrible illness. Keep in mind I have only just started 8th grade and for most of everyone it seems like this is the age peak. I’m back in school and it’s helping a lot!! Haha I felt like writing a lot because I really appreciate everyone who comments back to me💘💘
