Feeling unmotivated 😞😞

Any tips on how to stop eating so bad. I work in an office in the day and I literally eat from boredom on top of my bad eating habits in general. I can’t stop picking at junk. I keep letting myself down.. I say I’m going to eat better then boom I pick at something unhealthy. This is soooo much harder than I thought. Any tips?? I’m 220. Just had a baby 1 1/2 month ago. I use to be so much smaller and motivated!!!! Then when I became pregnant I got so use to sweets and my bad sweet tooth from my cravings. I just want to get motivated how I was before. I want to feel better. Why do I keep eating bad when I know I need to change. I feel like In a competition with myself. Please no judgments thanks ❤️
