Hello and welcome to PC
I have found that since being on my current medication combo I am happy all the time, like it has become a new baseline for me. It's not euphoric happiness just general happy to be alive happy.
I used to have terrible depressive states like couldn't get out of bed for days, like all the happy had been sucked out of me; granted I spent three months in the depressed state so maybe this is what happens when I am stable.
I'm sorry that you are suffering
