I need to find a familydoctor in my area that takes cash only/ sliding scale/ no insurance. I desperately need a checkup and check my cholestrol, etc.

County Health Dept. Check with your county or state health department. Most of them have lists of low cost or free clinics available for people in your situation. Also, check with st. Vincent de paul, salvation army, local churchs, medical or nursing schools, universities, etc., as they may have knowledge of clinics in the area.
