Does anybody else stopped doing your hobbies since u started?

I started therapy at a very good point on my life, but everything has changed, I feel kinda sad most days and left doing my hobbies wich was gym and kickboxing, I was pretty good at it, but I feel know that I dont have that thing that made me move all these years… I dont want to stop doing my thing, it defines me. I want to continue but now its like… harder… like I really need to effort to hit it. Idk how much time I need to heal this and just keep on with my life
