We all do this at times compare ourselves to who we were once.
The reality is when you were that person life was different, circumstance was different the people in your life was different. You were who you were them because of the place you were in your life at that moment.
You are who you are now because this is the path you have taken, don’t look back and wish to be that person again be it in mind or body or circumstance be proud of where you are and if you not happy with how things are then change it. You are always in control it’s just it sometimes takes a lot more determination and work to change but it’s possible.
Anything is possible if you want it, if you really want it.
Sending love and light to all
