I'm pissed at my family for not being supportive of my weight loss
Why aren't they supportive of your weight loss?
They have been eating fast food around me while I eat healthier foods.
I understand the frustration you feel about being around all that temptation. You should have a talk with them about how this makes you feel. Suggest that they eat out instead of eating junk around you.
I don't want to make a big deal out of it.
It's good that you don't want to make it a big deal, but they should still be supportive of you and not want to eat unhealthy food around you.
