Dear Octavia,
No, I don't believe Jehovah God is punishing you. I don't believe He is connected with Jehovah's Witnesses at all! That organization just took on His OT name. They liked the idea of calling themselves "God's Only True People."
But He allowed His Son to come to earth to show how much He actually loves humans, let him be ridiculed, tortured and killed to show how much He loves humans. So again, no, I don't believe He would make that demonstration of His undying love and then punish humans for being humans in association with a man made organization that exemplifies LACK OF LOVE, instead of Godly love.
Broken relationships are "killer" so to speak. They hurt like there's no tomorrow. But most of us have been through it at least once, and the intense emotional pain subsides in time and even goes away.
I'm still sorry for your pain, though, and hope you feel much better soon!
