worried about headaches

Ok so i guess im a natural worrier. Ive had IBS for 5 years and get worried about most things very easily. I used to be fine going to college, leaving the house and being alone, until i started getting panic attacks around a month ago. Ever since then ive had two really bad panic attacks. The first happened when i was alone, hence why i was scared being alone, the second was so bad my mam had to call paramedics and eventually after about 3 hours i calmed down. The usual symptoms of my panic attacks occur: chest pains, trouble breathing,dizzyness, pins and needles in hands or feet, fatigue, choking feeling and im sure theres a lot more symptoms others have had. Lately i have been worrying more than usual, and have been going to therapy to sort out my IBS and fears of dieing etc but i have only had two sessions. I also have medication for my worrying. Its called Kalms but at the moment i havnt seen much effect. The reason im on this site and posting is because ive been having some headaches that have been worrying me. I used to get a sharp pain on the centre of my scalp, and then this lasted for a couple of days, and then dissapeared once i stopped thinking about it. For a few days ive had a pain in my temples, either side or both at the same time. My mam told me it was probably just stress headaches, took some painkillers and was fine for a bit. But then the pain came back in my temples, but also in my forehead, and the sharp stabbing pain came back and also at the back of my head. I also get pressure around my head, usually on the forehead and on the top. I read a site about the symptoms of a brain tuma, and it said dizzyness and pressure in the head. Now this worried me because i had been feeling dizzy and had pressure on my head. i havnt seen a doctor about this yet but i am in 4 days from today, which for me is to long. I dont know if im just worrying over nothing, or whether this is something serious. Ive research on the web and something like sinus infection might of been the cause, but the pressure isnt just around my eyes or forehead, its also on the the top so this is partly why im worried. If anyone could help me out that would be fantastic, but if you need any more information then please ask. I always feel like im dieing and i hate it :(

along with dizziness, i get the feeling of pressure or an inflated feeling above my eyes and on top of my head. its creepy and of course i think of worst case scenarios. im a natural worrier. i get panic attacks too. i found a thread on another forum about it and the only person who responded with a diagnosis said it was a sinus infection. good luck im just as eager for an answer as you are
