Hi, I'm a 20 year old from Toronto, Canada.. I could really use some help.. if theres anyone out there..

I'm actually on the way back from visiting a ex girlfriend, and it didn't go so well because it emotionally and physically killed me.. it brought back too many memories etc.. and I havn't moved on yet.. even though its like years that we've broken up.. I'm going to go see a psychologist when I get back.. but thats not the real issue here..

I've been getting these headaches for a few years now and it started around like left eye.. and I believe it made it lazy a bit.. and then 2 years ago.. a bump appeared on the top right of my head and its been getting sore and giving me headaches like crazy.. it seems to affect my right eye.. My vision is getting worse even though I don't need glasses.. and whenever I exercise or don't eat right or don't drink enough water the headache and area hurts sooo much, and it seems to go from the top of my head to my neck etc.. its weird.. and Never really seen a doctor about it..
If you could please help me explain this situation to the doctor it'd be great I'm thinking of heading to emergency tomorrow as I don't have a family doctor neither can I find one...
If anyone else even has a clue what it is either please let me know.. if I can this pain/issues with my eyes etc gone I could happily get on with my life and MOVE ON!!
Thanks dearly.
