Not that I really care, but I think that getting out of the hobby because you have lost fish is childish. We all lose fish.
Do not sell your fish. You are a grown man, things happen in life. Tomorrow is another day.
Things in my life are not real rosey right now, but I am not going to sell my fish and kill myself.
In all seriousness if your are a TRUE hobbiest, bury your fish and move on. You seem to enjoy your fish, it would be a missing part of your life.
See how you feel in a few days, do not post your fish for sale.........patience and calm.
