I think reading all of these threads makes you realise you are not alone and that a SAH can have many different effects on the body although there are several common and recurring themes. I had my SAH in Sept 2010 and fatigue is still my biggest problem. As in other replies, I think you have to ignore feelings of guilt or embarrassment at going back to your doctor - after all, this is your life they are playing with and it is not to trifled with. You know your own body best! What I would suggest, as others have, is to keep a diary of how you feel from day to day - hour to hour if necessary including the following:
1) How you feel now both mentally and physically [record sleep, depression, therapies, work pressures etc]
2) How it is affecting you now
3) How you felt before your bleed
4) What is different from then to now [ie measure the impact on your life, treatments,drugs required, support from family members friends etc]
5) Anything else you think might be relevant
In this way you can quantify what is wrong/different - show it to your doctor - it is easier than trying to expain it or remember specifics in a 10 minute doctors appointment.
Before you can successfully treat your problem you have to fully understand what it is, from what you say I don't think you do yet, at least not to your own satisfaction. You sound like such a giving person with a conscience, it's time for others, inparticular the medics, to give something back to you for a change. Get back there and demand more answers and don't let them fob you off - you are not a nuisance, you are a precious life with so much more to give, so do it to help those around you and most of all, for yourself. If you upset someone, then so be it, you can always apologise afterwards - get yourself better first - PLEASE!!
I really hope this helps you and you find the answers you are looking for. And the members on this forum are always here to help and support you.
Good luck
