How can i get my motivation back?

I used to work out a lot like 4-5 times a week and i used to eat really healthy. I really loved doing those things because it made me feel better about myself. I was really committed for a year but it’s been a year and a half since i lost my commitment. I know how to work out and eat healthy but i just lost the feeling of enjoyment and commitment.

I’ve tried a million times to eat healthy again and work out and to get committed again but i have a lot of excuses not to. I know the excuses are bullsh*t but it’s hard to avoid excuses

I’m just stuck right now and i don’t know where to begin. If you have lost motivation and had to get it back, please tell me how you got it back and how you stay committed.
