I can’t shake this anxiety and idk how to

I have this anxiety of how much I wish I could go back to being a kid knowing what I do now. I wish I could start my life over from the age of 10 but remember everything. All of the things I would do differently is killing me. I’m 24 and have nothing to show for my life. I am waiting to apply to my program this year but I haven’t done anything with my life. I have literally watched tv and stayed home bc I was tired from working during my teen and young adult years. Now the only friend I have is in her program and busy all of the time. I have a hard time making friends and I am so bored and unsatisfied with my life so far. I have little hobbies that I do but I’m tired of them. Idk what I’m looking for here. Just a rant I guess. 🤦🏽‍♀️
