Basically, my younger son estranged himself almost 5 years ago with no explanation so I definitely empathize with you and your situation. I’m so sorry for the heartbreak and loss you’ve been experiencing. This has caused me deep anxiety and depression over the years and I went so far as to commit myself to a mental health facility. No rhyme or reason to it. He had a great life. Was a great, quiet kid. No drugs or alcohol. Just decided one day to cut the whole family and move away. And he keeps moving. I went to his house once in the beginning and he refused to open the door or talk to me. We hire a PI to find him for peace of mind whenever he moves and the last time called the police for a wellness check. It gives me comfort just knowing where he is. I pray one day he comes back. Maybe he’s dealing with his own mental health issues. I wish I had advice for you. Just a hug and pure understanding of what you’re enduring. Praying you get the peace you deserve. No parent should have to experience such devastation from a child they raised with love. 💕
