I am so sorry, pas. Of course you are hurting for him and angry with him as well. And for yourself, as his mother, it is hard and sad and maddening to see this happening to our kids and not be able to do one thing to stop it.
Most of the time they don't keep them as long as they can, for the simple fact that it costs a lot. Here in our state we have a 30% rule, which means that whatever the sentence, it usually gets reduced by 30%.
As your feelings move from this shock into thinking about the future---with this situation---think about the fact that he is off the street and in a safe place, as much as it is.
You can write him letters of support and encouragement and aspiration and he can sit with those letters and really take them in, much more than conversations.
You will have some relief for a while, pas. I am glad about that for you. You need time, too. Time to heal from the relentless stress of this.
And maybe, just maybe, as he gets a few months older, and he has time to see where he has landed, really, he will be ready to do something new. That can start in jail---it doesn't have to wait until he gets out. There are many programs in jail that can help one become more equipped to deal with the outside world. Maybe he will take advantage of those and learn some new skills.
Often, I have found that after my initial anger, despair and grief have passed, when my son gets sentenced (again and again), I also start to notice a new calm and a new relief.
I hope you can find that too. But I am sorry too---I am sorry it has come to this for your precious son. Please keep talking to us about how you are feeling. We care.
