Anxiety - adult

Hi

I have a 40 year old son who suffers from extreme anxiety. In the last 12 months, he has split from a very supportive partner, became homeless and tried to take his own life. He is now in a flat, money is very tight and now he faces a review of his PIP, so again he is severely anxious and overwhelmed. He is autistic, has ADHD and PTSD.

We have tried him living with me and his step father but it didn’t work for any of us. For the last 12 months we have supported him 24/7. My concerns are that we are not getting any younger, the strain on our own mental health is very negative; I struggle to sleep due to worrying about him, but my biggest concern is - who will support him when I am gone? 

He has an important job with the NHS, for only about 14 hours a week - this gets him out of bed and he is very capable most of the time at work, but anything outside of that he can’t seem to cope with from a relationship breakdown right down to simple admin and all things in between. Therapy over the years has not made any significant impact 

is there anyone we can go to for advice please. I worry that I have provided too much support, when I should have somehow made him stand on his own two feet. It’s hard though when you get those phone calls in the middle of the night when he can’t cope. 

Any advice would be appreciated. I’m hoping I’ll be around to support him for many years to come, but I’m not immortal,
