Symptoms?
 

ok these are my symptoms and im worrying myself stupid because they do not sound good to me.

Kinda urgent.

Ive had headaches for weeks
sight in left eye keeps going funny
wake up with nosebleeds.
last few times ive purged i have collapsed on the floor.

my glands feel funny, my throat is sore, but thats probably from purging.
Its the headaches/ nosebleeds/ dodgy vision which is really worrying me

what do you guys think?

I think you need to see a doctor. Without doing a physical exam on you it's impossible to give you an idea without a lot of guessing/assuming.

I'd go and see a doctor. The purging/nosebleeds could be related because when you purge you can irritate your nose which then you might knock in the night. Though, thats only guessing and it may not be. The headaches along with the vision probs might be a migraine. However, like I've said, these are only guesses and you need to get checked out
