I’m worried I have a brain tumor, I’m 17 and worried   about 6 months ago I smoked weed with my girlfriend and I had a panic attack (never had one before didn’t even believe it was a real thing) and every day from then I had chest pains, out of breathe and loads of other heart problem symptoms I had an echo cardiogram and I got the all clear ever since I havnt had a single pain since but mean while that time I was getting headaches which made me think I had a brain tumour but I was to focused on my heart to even worry about it, now I have got no chest pains but now I’m getting back of headaches every day eye twitches left eye 

feel like I’m like forgetting what I’m saying then remembering again I wake up first thing I think is do I have a headache I don’t then one just comes my headache is in 3 places every time corner of back of head back of head and left side of head, Iv been the doctors they said that they arnt symptoms of a brain tumour and I have health anxiety (i seen them about 20 times when I was worried with my heart) I also seen my opticians and explained to them they said it’s becauseI’m not wearing my glasses, they checked behind my eye said I had no swelling but I know this isn’t 100% accurate  and my eyes are dry so Iv started wearing them 2 weeks and not much change if anyth g they have got worse (the headaches) I don’t know if it’s worth pushing for an mri like I did with my heart or just trying to forget about it but I hate these symptoms I’m worried so much again it’ killing me if I have a massive fear of death makes me wanna cry just thinking about it I’m a tough lad never believed in anything like that and now I feel like I’m having my life ruined I’m constant googling symptoms and sounds stupid but I google symptoms and I feel like they come true I just don’t know what to do I can’t cope doing this again it ruined my life before I had about a month of f getting about the situation with my heart please if anyone could give me some direction or reassurance would be much appreciated thankyou it just worries me that doctors can get it wrong as my mom h a burst appendix which turned into sepsis and my mom went the doctors about it which they could have stopped
