Sometimes you just have to go through a liminal phase where you feel like you don't really have a direction or just can't get where you want to go. Over my life I've started to understand that's just the way things are. Nothing changes until I'm ready to change it. So if I just accept that I'm stuck in that liminal phase it seems to help me get out. Eventually I find a project I'm interested in and that gets me out. Weight lifting worked for me to get me out because I could see the actual progress literally in the numbers on the plates or the number of reps I could do. That kind of positive feedback made me happy and feel like I was making progress somewhere in my life. It also taught me to prioritize sleep/recovery and protein, two things that have made amazing improvements in just feeling great. Maybe some other kind of project would work for you.
