Hello I'm a 28 year old male. So I would like to start out by giving my back story of how everything happened;

around April time- I was watching tv late at night at my girlfriends and a cancer awareness advert came on- and it struck somthing in me that I felt so bad for the person on it. Anyway I went to sleep and in the morning I was driving home to work - And I couldn't stop thinking about the advert then all of a sudden I think I either had a panic attack or anxiety attack thinking this can happen to anyone. After this my moods changed and my way of thinking changed - before I had never thought anything could harm me- now I'm convinced I have a brain tumour and that I won't live long enough to have kids, and I feel like I'm constantly down and depressed now and feel so sorry for my girlfriend 
 

so after that, I started to get headaches and ended up getting my eyes tested in may to see if this was the cause for them - the optician said that although I need glasses for work- this wouldn't of caused headaches becuse the thing that's wrong with your eyes would of been like this for years and not just sudden. So I ignored it and my headaches came and went (roughly 4 days a week on average) which was still worrying me because before this I had never got random headaches before in my life. 

Last month my dad passed away - and my headaches came back and now I've had a headache ever since for the full month. I have other things also which I'm not sure are tumour symptoms but I get random pains both in my joints and muscles around my joints , depressed ,, random pains under my arms, really lethargic - I haven't got out of my bed for atleast 4 days now. 
 

i let my gp know about all of these symptoms on Monday and I I am going to get my blood taken today but this worrying is making my life hell at the moment, I can't take care of my mum properly from my dad passing because of it
