Joking aside Guy. I get these ups and downs. I think it's normal. Like everything..has a cycle. One minute your hot..next..not so much.
Like the plants getting hotter and colder. The tides rise and fall. We too have better days then others. To be happy all the time means big pharma got to you. Natural to feel good and not good the next day. Too often though..You might wanna talk to a professional.LOL
I don't believe in those professionals..Family and friends who care for you is the best solution. Not some cold shrink who's only in it your that house or boat.
You'll be fine. Takes a thought to get out of a thought!!
Good luck!!
