Unhappy with new job

I've been reading allnurses.com for awhile now, but this is my first post. I'm a new grad LPN and I just passed my NCLEX @ the beginning of August. I just started a new job as an LPN @ an ALF on Monday. I've only been there for 3 days and I'm already not happy working there. They have med techs that pass meds and they had me follow one yesterday so that I could get to know the hallways. I saw them doing some very unsafe things that I, as a nurse was shocked at (I don't want to turn this into a debate about med techs). I am hired as a nurse, but I am doing things that the aides are doing (i.e. cares after meds, making beds, cleaning dishes off tables after meals, etc...). I have now problem doing these things b/c I was and aide in an ALF while I was in nursing school, but I was not told that this was going to be in my job description when I was hired. I was told I would be doing more of the nurse stuff since they on have maybe 1-2 nurses (@ most) per day. I am already stressed out about this. Last night was horrible I just kept crying because I just don't know what to do about the situation. This morning I started crying when they wanted me to pass meds by myself. I just don't feel comfortable passing meds to residents that I have never met or only met once. I've put in some applications for some doctor's offices (which is what I would really like to do), but I don't know how long I can do this. I've talked to some people that have told me to go with my "gut instinct" and quit, but I hate to quit after only working 3 days and with out another job lined up. I'm just not sure what to do any advice/suggestions would be welcome. Thanks in advance!!!
