My youngest son who has been my best friend for 38 years had not spoken to me in a month. I said some things that hurt him.. not intentionally but he declines my calls won't answer any texts. He said he needs his space and time to heal. I am trying to respect that but he called me every morning for the last I don't know how many years now. I'm afraid he won't speak to me ever again. I sent a letter apologizing with his wife and also took responsibility for causing him this sorrow. He had not even read it. I'm not doing well can't even get out of bed. I drag myself to work.. can't shut my mind down to sleep. Overwhelming  grief and crying. I don't feel like I can get through this. Need help
