How nice to read this friend, I am also very emotional and I have felt those peaks of very high and low emotions, I also calm down, I try to breathe, I talk to God and I try to connect with my inner being and I tell him that everything is fine and it's going to be alright. Greetings and thank you for sharing your being with all of us. Blessings.
I don't believe in God, but I totally get what you mean. For me, it can be connecting to the divine self, or the divine behind the ego self - I do think that's almost the same thing. I'm glad this works for you.
I understand friend, the good thing is to connect with our inner being and seek peace and harmony.
