Am i selfish??

My birthday is coming yet i dun really feel well, not only becos im sick but also becos i dunno how to split my time between my girlfren, my frens, my cousins and also my family members.. I tot of having a chalet where everyone could gather making things easier but tinking tat maybe there will be different gruops of ppls cos they all dun really know each other.. Being 18 is kinda impt to me XD but in any case i tot of spending time with my gf on my actual b'day itself.. But of cos i would really like to spend time with my frens and cousins as well since there is somethings i wanna do tat my gf will nv like =((
