The closer I get to my MRI date the harder it is for me.
For this past week I've been through all the emotional stages of accepting an impending death.
It's really messing with my head right now, only a few more hours to go and I really can't think about anything else (besides my MRI).
Symptoms: Thursday the 31/1 :feeling tired and sleepy all day, took some caffeine pills to get me through class, woke on friday (1/2) at 4 am with ''the worst headache ever'' couldn't think or do anything for about 2 minutes, took some ibuprofen , headache went away but still feeling this ever present pressure on top of my head that manifests in different ways:
1-sometimes it's on top of my head, like tingling/pressure
2-sometimes it's on my right temple/side of my head like someone is pressing his thumb on my head.
Been to the doctor the same day because I googled and was almost sure I had a tumor/aneurysm/stroke , doctor did a physical and gave me some blood work to do as a follow up of some previous test and sent me home, said I was fine and to come see him if it started again. (the pressure never went, the headaches never reoccured).
Then the worst weekend of my life happened, basically didn't move from my bed, just googling away, over these 2 day period I haven't left a single website abotu brain tumor I didn't visit.
On Monday I got the blood works done, results are all fine except for a slight hypercalcemia for which I'm going to see my endo on friday.
I CONVINCED my doctor to get me an MRI which he eventually agreed to (scheduled tomorrow).
The past week has been very on and off but I'm very depressed, convinced I'm going to die, I neglected class work, I probably gained 5 pounds from all the overeating because of stress but what's worst is that the head pressure is STILL ever persistant.
So basically right now asking for advice/googling symptoms is useless considering I've got an MRI in less than 24 hours but I'm scared of what the possible results will be.
My googling shows that my headache show the symptom of a bt one: is constant and dull, gets worst on one side from time to time, gets worst with bowel movements and exercise.
I'm really scared of a positive diagnosis tomorrow and it's making my head ache ever more

Can anyone help?
PS forgot to add: I took some codeine the day before yesterday to help me go to sleep which landed my in the ER due to an allergic reaction, really didn't help alleviate my fears of getting a positive diagnosis back or my health anxiety in general.
