This is a very good post with lots of different input,I haven't posted on as for a long time but still read. If it's just pinball that is stale don't be too hard on yourself ,it's just a hobby but if you aren't getting any enjoyment out of other things in your life that's a more serious situation. Identifying what triggers your emotions etc fun ,enjoyment,boredom will assist with what's going on.
Ask your friends and wife to see if they notice any difference in your state of mind or behaviour. If it's just pinball don't stress but if it's loss of interest in all other things
It may need a little more investigating.
Don't be too hard on yourself though. We all take time to regroup and repair. Medication isn't the be all end all as brains all react differently to the meds, when it becomes serious it's a combination of exercise,healthy eating,mindfulness, medication, counseling,therapy or what you want to call it . Hope your feeling ok today Smithy.
