Welcome Justrose and Dodee
You are not alone. I have been here on this forum for over 6 years. My son is now almost 33. Everything you are both enduring applies to us too. My son is homeless unless I house him, and receiving SSI, which he uses primarily to buy marijuana, cigarettes, other forms of nicotine, caffeine pills, energy drinks, and what else, I don't know.
I could never have imagined I could tolerate this ongoing, but I have to, and I do. If I had to do it over again I would have done whatever it took to lessen the stress on myself, my emotional and physical health.
The important thing to remember is that they are separate people from us, our children. At this age although they want to be dependent upon us (while doing exactly what they want in their lives, with their bodies, with us and in our homes), they are no longer our dependents--they are autonomous adults. We are not responsible for curbing and changing their behaviors or forcing them to be better or do more. Trying to make them do anything is impossible. It only tears us down and brings us to despair. Any change will come from them if they want it when they want it.
I am the only one of my friends who has a child so problemed. While I don't do the Facebook thing I do feel bad because my friends' children look after them, help them, offer companionship, and are a source of pride--instead of stress, worry, fear, sadness, and worse.
I feel guilty writing this because I love my child with all of my heart. But it's the truth.
I fantasize about some future time when my son can again be a companion, a source of pride and joy. But that person is not who my son really is, as an adult. For the longest time, I thought that if I could not get him to change, then I would have to, and come to accept him as he is. But I can't, at least for now. It costs me too much, emotionally, because of how selfish my son can be with me, and how uncaring.
People urge me to "accept." But how to accept that a child lives a dangerous and degrading life?
After all, I love him so much. I don't have the defenses and don't want to have the defenses it would take, in order to be with him, the way he is, for now.
I didn't mean to write a post like this. It just came out of me.
For the longest time, I was tethered to my son like a Siamese twin. I was just tortured by it. I have finally let go. Not the way some parents have, which is a hard stop. I'd say it's a "soft stop." We are in contact when he wants to be. He's staying right now for a couple of days in a property I own until his SSI money arrives on the first. But I have no real investment in any change on his part.
This isn't to say he won't change. He may. But it won't be on any terms or timetable that I set. The way I see it, hope is mine to have--it has nothing to do with him.
I have gotten a great deal from being on this forum. Most of all, the people here have been companions and great support. They know me as well or better than close, lifelong friends--perhaps better--and I have never met them, and know few of their real names. There are a few members who've been here longer than I have. I feel so grateful that they're still here with me. I've tried to back off from posting, but I miss it when I do.
Once again, I welcome you and urge you to keep posting. You are not alone. There are people here who understand and who care.
