I have no motivation to eat better

I wouldn’t exactly call this depression in the usual sense. I feel happy, but yet i have no motivation to eat better. I go to the gym, i go on walks. I feel happy. But my life is horrible just because i can’t eat better and have no motivation too. My mom can yell at me all she wants but yet i dont feel it. I wanna eat better. But theres nothing i like, everything tastes shitty, and i dont wanna eat it even if it’s good for me. Everything that is bad for you i almosy exclusivley eat. Pasteries, potato chips, french fries, pizza, ice cream, and honestly not much else sense i eat like shit. I can’t eat better i just can’t. It’s sucks. I suck.
