I think it does. My depression sarted about 4 years ago and i tried to ignore it, didnt get any therapy and it just got worse. I was strong enough to carry on with daily life more or less, but i cried when i got home, wished for nothing more than being dead and my body refused to carry on. I got headaches, they went so bad i couldnt get to school anymore or do anything. Meds didnt help for long, the headaches were there all day, nearly every day.
I saw a doctor and he thought it was lack of vitamins, but after taking vitamine pills they didnt stop, nothing helped. i was already worried it might be brain cancer or whatever, i was scared cause i had no idea where it came from.. Now im finally done with this horible school, which i guess was a main factor of increasing the depression.. and i was pretty shocked that they are just .. gone.
For almost two month i didnt have headaches anymore, just perhaps one or two days, im pretty sure it has to do with the depressions!
