i'm being torn in a million directions

i need to vent in a safe forum. i moved cross country 7 months ago, spending almost 10k, and taking a 1000 dollar a month pay cut from my job at the time to help a few friends with their ebay business. it was family run, and last friday, words were spoken, feelings were hurt, and the business was torn apart. now, i am being told, that i will eventually be asked to walk away from it all. but it is not that simple. i do not make enough money from the job i have now to pay my bills. i needed the ebay income. my friend knows this, but she feels her loyalties should lie with her. i respect this, but i have bills to pay at the same time. i feel i am being put in an unfair situation. i feel that the problems they are having should not have anything to do with me. if i had known this would happen, i would have never made this move. if i give up this business, i would then have to go get another job, possibly working more hours than i could physically handle at this point, just to make ends meet. i am worried for the friendship. but, i have my bills to pay. i don't have family and friends that would help me out. it's just ME. i don't think that my friends and family realize that. i am usually "the bank of karen" but when the well runs dry, there is no one to "refund" or help the bank of karen. that is always why i have to be so careful with money, and always have to plan way ahead. most people think i'm crazy, but it has to be, or the bills don't get paid. it has always been a scary place to be, but it has been like this most of my adult life. i have to do what is best for me, not others, as i have so often done in the past.
wish me luck, i just needed to vent.
