I am an ex-addict. The first thing exes learn is to swap addictions/fill the void. You gave what you were swapping out for. Less martial arts. More God. Now you're bemoaning martial arts? It's what? A day? Two days? Were you planning on filling the void next year? Next decade? No. Really. You fill the void immediately.
Discombobulated I get. What you sound like is someone who is planning to sit on the sofa until something shows up. What was that purpose in giving up martial arts really?
And it's martial arts, for Pete's sake! This isn't "I lost my house in a fire," "my spouse cheated on me," "I just found out I have a serious health problem," "I can't find a job," "my dog died," "my roof is leaking and I can't even pay my bills, once more get it repaired," nor alcohol addiction. It's martial arts. But you want great sympathy? What happens when a real crisis hits you, if you think this is a serious dilemma?
What do I feel now? About the same as I have felt for the last 38 years. (I think I've had every feeling multiple times since then. I don't really spend much time sitting around figuring out my feelings to know.) Life moved on and I kept going.
