Changes from a posting place

How do I make changes from a positive place? My mind keeps turning back to: I’m not enough. I need to make these changes now. There feels like such an urgency to get to it and get it done. And that the same time, I feel like I’m spinning my wheels and trying to force all these changes such as making more money, not eating junk, loving myself etc. I’m also getting married so it feels like I need to make all of these changes by the wedding otherwise I’ll be over weight, broke, and feeling unworthy. It just feels like I’m a mess.
