Sharing Our Innermost Thoughts

Idk I feel like I’m becoming worse version of myself as I’m growing up. I had this evolving, “I can solve/do pretty much anything if I decide to” mindset but now my mind don’t seem to be that active, energetic and motivated and it sucks. Now, for the past few years, I’m not even able to do tiny things that I must do and I’m questioning myself now…am I still the same person I used to be or have I turned into something which I never thought I would be?
This thought is scary because current version of me will decide future of me.
And I don’t why it feels like it’s not in my hands to change it anymore.
I’ve lost the spark.
