Advice on being healthy??

So lately I’ve been trying to eat healthy but it’s so hard when all I want to do is eat anything and everything I see. Since it’s the holidays, I can’t just restrict myself the entire time or else I’ll pretty much ruin everything for me. My parents constantly come home with unhealthy food and even though I know it’s bad for me I just can’t force myself to make a better choice. Even if I do, I end up eating bad things even when I’m not hungry! I just can’t get away from my cravings. I’ve gained 5 lbs in November and I mean I know it might not be a lot but considering that I know for a fact I haven’t been eating the cleanest, I know it’s probably not healthy weight. I’m trying to workout more since I used to do it regularly but now I’ve been slacking. Basically, my eating habits and workout plan hasn’t been working out. It’s been a year since I’ve tried to do something but after i hit a sudden plateau in May, I can’t get back on track. I haven’t made much progress. I mean, I lost weight but I don’t feel great internally nor am I really satisfied with how I look. I’ve been stressed constantly because of school and i barely have time to relax.

I’m just so confused on how I could get myself motivated and actually have a more realistic plan that I could continue now and for next year. Any advice?
