am I still a good person, do I want to be, do I need to be? wtf?

Ok Cell seperation just called, this marks 6 months from my last official nose bleed. This raises important issues for me, and I am not sure if I am ready to think about them at the moment.
For those of you know dont know what Im going on about, Ill fill you in on the details (briefly).
I am a wimp and so to get over my fear of needles I started donating blood. This seemed to work, I fainted the first time but since then no problems.
So as I am a very fit healthy kind of guy, in spite of excess alcohal on occasion, I got invited to join the cell seperation part of giving blood. After a few tests I was put on the list, so for the last 3 years every 4-6 weeks I got a call when someone needed my plats. I spend 2-3 hours on a multi needle machine that sucks my blood and takes out all the goodies they need, which get shipped out to someone who needs them, from what I understand its normally a cancer sufferer or burn victim. Its a lot more personal than giving blood as it is going to one person who needs it right away and it takes a whole lot more effort and time than donating blood.
This leave me feeling pretty knackered for a day, but is good for karma man kind etc and gives me interesting needle marks on my arms. These are always of interest when I visit a doctor as they ask about drug usage looking at my arms.
So as anyone who listens to the news is aware blood services are pretty fussy about who's blood they take.
No tattoos, piercings, ritual scarings etc
This does not effect me as my body is still pure but there is still the sexual partners question. This is always akward, as they phone, so someone needs my plats, then I have to explain how I just have a new girlfriend or whatever. An event like this is termed in the industry a nose bleed, and they give you a 6 month break so that if you are going to get AIDS your body gets infected enough for them to spot it.
Its been six months since my last nose bleed, the late night calls from psycho ex have almost stopped and I have to decide if I am still a donar. the whole thing is like a marker board. Passing of time, change of mindset, priorities etc etc.. ow dear way too much to worry about while I am late on an assignment and my head is full of object orientated programming stuff, not to mention the rest.
