Hi. So I'm a 18 year old girl and I've been told by my doctor that I have anxiety. I've just started to see a psychologist to help me get through this. I've always been an anxious person since I was a kid and this summer I woke up with what my mother called a panic attack, with my heart racing, I was really nauseous and couldn't breath I though I was having an heart attack and that I'd die. I've felt more anxious that the usual since then, everytime I get some "sympton" I search the internet and I get afraid that I have some disease or that I'm having some attack and that I'll die. I've got good hours and bad hours and they change every time. About 4 months ago or so I couldn't sleep at night, I spent hours without sleeping and some nights I didn't sleep at all because I was afraid and I felt like I couldn't breath and I wouldn't go to sleep before checking my tension.
I've always been afraid of the night and the dark for no apparent reason and I have lots of nightmares where I'm chased in the dark and can't come home. I went to the doctor and he told me I had anxiety and that I should use medication when I couldn't sleep. Every two weeks I go to my father's home with him and my sister and the trip takes about a 1h or 1/2h by car. I can't go without feeling really anxious I always have to open the window and close my eyes and listen to music so time goes faster.
One time my head felt so weird I thought I was going insane I felt I was losing my mind and didn't belong to this world and I can't explain it right.
I can now sleep better and without the pills but my issue is now every single day at afternoon, usually starting at 14h/15h I feel so tired. My head feels heavy, my eyes feel pressured like I can't focus or that I'm not really seeing what's in front of me. I've got small headaches and the top of my head feels like it's beeing squeezed, I have this sensation when it feels like someone's sticking needles in it. I've also had pain in my back, most of it in the shoulder blades's area or in the bottom of my neck.
This is affecting my life a lot since I'm always picking up my sister at 16, 17h and as I'm walking I feel really dizzy and drowsy and like I'm not there or that I'm gonna faint. When I get home I can't seem to to anything because I have this weird sensation in my head and my eyes and it feels like I can't understand people or following the conversation they're having with me. I sleep well, have a sleep routine so why am I feeling like this? I'm afraid I have some tumor or disease and I always end up looking for answers in the internet please help me
