Late night with music on SAD

So..right now i'm jamming out at a time when i should probably be preparing for sleep..if not in bed already..
the problem is i don't want to..as much as i dislike this holiday for what it represents..and as much as i'd like it to end..i can't bring myself to go to sleep..
my mind right now is racing with so many thoughts..i'm not quite sure where to begin..
i'm trying to get over a couple of rejections by some amazing girls who've decided to get boyfriends in the past weeks without bothering to tell me..not that they needed to..it's the only good reason for a girl to reject a guy in the early stages of a relationship..and yet still painful nonetheless..plus trying not to lose my friendship with them..just in case..well you know why..
this little problem of getting over women is only compounded by the fact of how often i hear preached about going on dates and finding one's eternal companion..the pressure seems enormous to not be messing around at a time like this..but it's not my fault they say no, is it? i've got a couple of gift certificates and other such stuff that were given to me specifically for the purpose of dating..and not to seem shallow or anything..but if i'm gonna be dating for marriage, i want to date girls that are potential eternal companions that have certain qualities including, but not limited to being really attractive..and unfortunately for me, this greatly reduces the pool of girls already made slim by the workings of other men on the planet..
i might be able to sleep better at night if this was my only problem but it's not..i've also had this feeling since the end of last semester that what i'm planning on doing with life is wrong..right now i'm majoring in accounting and getting my premed stuff done too..then move on to med school and become the world's best doctor..for one reason or another this just doesn't seem right to me..and i'm not sure why..
another problem is that i'm not quite sure what to change it to..the list of options goes on..from engineering to teaching seminary..and many things in between..
these thoughts have been running through my head all semester..keeping me awake and miserable..
my only respite from these thoughts comes through music..i lose myself in it..trying to forget for a while what's going on and postponing the decisions that need to be made and the things that need doing in my life..
sometimes i can also lose myself through physical exertion..because when my body hurts..by emotions won't..this doesn't happen very often though..because of the amount of work required to make my body shut down is almost more than i can manage to do myself, it takes at least a couple hours everyday doing sprints or something else strenuous like it..if i could just figure things out..then just maybe i'll be able to truly sleep at night and not have to worry about all these things..then i could probably get out of bed in the mornings in time to actually do important morning hour things..like eat breakfast..
well..i'd best be off to at least try to sleep..maybe i'll be able to prepare for tomorrow and figure things out..and hopefully it'll be sooner rather than later..
