I stay happy by being involved in the things that interest me like my husband, children, hobbies, online, ect.. I have 2-3 hobbies that keep me going.
I'm pretty happy even though I've gone/going through major painful health issues. It took about 3 years to accept my severe chronic pain. I have a very supportive husband. Without him I would not be as happy as I am now. It helps that my husband supports my hobbies as well even though he is totally disinterested in them.
