facial hair, everywhere!!!

I don't know what the he'll is going on but lately I have been growing lot's of facial hair under my chin.. my sis thinks it's the frozen tv dinners I eat when I'm at work and that I microwave a lot of stuff too (she thinks its a radiation thing?) I went to the doctor and she TESTED my blood to see if I have extra testosterone turns out i don't and she basically told me to get laser hair removal. but that stuff is hella expensive!!! so what can I do too get rid of the hairs? I can't tweezer forever. help its so embarrassing!!!!!
