Welcome the raysmom! We all know what you are going through right now and can sympathize with you. It is hard to let go. Your emotions will be all over the place for a while. I was told by a counselor that it is normal to suffer the symptoms of grief in this situation. You need to grieve the loss of your relationship with your son, because from now on you will have a new relationship. So cry when you need to, but remember to focus on the positive and not the grief. Join any groups that you relate to and anyone in the group will be glad to help you through this time.
Be very proud of your seaman recruit and when you do get to talk to him remain POSITIVE for him. Sometimes it is very hard because we can no longer "fix" our children's problems for them. But you being POSITIVE and upbeat (no matter what you are really feeling) is THE best way to help your son. Keep reminding him of his goal and how great it will be for him. It takes hard work and focus to get through the schooling but once he gets to his 1st assignment and is able to do the job he is trained for, it will be fine.
My Sailor has been in for 4.5 years now and has had both ups and downs. But for the most part the Navy has been a very positive thing for him. He has excelled in his life in ways I know he would not have been able to before enlisting in the Navy. It has been the best decision he has ever made.
If you need a shoulder to cry on or just an ear to listen to you, let me know. I have been where you are.
God Bless you with the strength and comfort you need.
