Hello qwerty9191, have you tried very fun activities such as going to the beach with your children, family or friends? Or bike riding for example?

I'm no expert, but I have found out from personal experience that excersising many of these activities make you feel very happy and also train your mind on a sence feeling capable of doing things that require training, dependability and a sence of being able to accomplish something, pretty much will keep your mind busy and in return bring feelings of happiness.

When I go on my bike trips I know when I do laugh I laugh with all of my happiness, because of the endorphins and adrenaline released by such physical activities.
