Internal Conflict

So I guess my internal conflict would be lieing to my mom all the time. When I'm doing it, at the time I obviously am happy that she believes me, but afterwards I ALWAYS, end up feeling so guilty about it. I end up getting in a fight with myself because I know it was wrong to lie to her. I hate when people lie to me, so I shouldn't do it, and thats the main reason I feel so bad about lieing.
