Healthy diet problem

I’m currently trying to eat better and cut out the bad stuff I normally eat.. the problem I have is my parents keep buying the unhealthy stuff and it kinda just sits there and stares into my soul. I can look away but my problem is once I finish off all my healthy stuff I’m only left with the bad, I don’t wanna starve and not eat anything but I have nothing healthy to have. Like today I had a sweet potato for breakfast but I’m hungry and I’m only left with bad options and idk what to do about it.. do I skip lunch and wait to see if I can order a “won’t destroy diet” meal or do I just eat what I have and just say oh well until I can go shopping again..
