I wonder what your personal situation is? Are you working or retired, are involved with lots of things or have been leading a quiet life up until now? You obviously want to help them all you can , but this will have been a very big change to your own life and you do not see a time limit on it , which adds to stress. I have a married couple friends , who suddenly had to be in charge of a quite serious situation, and they were just retired and coping with their health but various problems. The situation was making them argumentative and upset between themselves. I suggest that they might first have one weekend a month off each. They worked it out and did do it. The man went to a yha and went walking, with gave him that little personal time, the woman had a friend of long years standing and a couple of times they got a twin b/b at the sea and another time in a city and went by train and it was a real break from driving and shopping etc etc. That did help them to get through the patch . and we tried to help the person staying at home. So I took their charge out for a day etc etc. Even if you only had 1 day out on your own, I think you would find it very destressing and does not need to cost a lot. I go to art galleries, parks to just enjoy sitting with a book if it is warm enough. If you have a river or stream nearby , I find the sound of water very soothing and when I am not able to walk properly I take my chair and sit by the water. This does not appear to be any assistance but I do think if you have these little breaks it allows you to cope with the rest of the time in a better manner and on bad days you can at least look forward to your "day off " If you have any health problems yourselves this would seem to be important to let you continue helping the situation. All of the other peoples suggestions seem very good, but if these young people have a specific disability I would look in the library for the contacts in your area. If you get to the right people they should be able to help you through the maze and tell you of any local help that may be available. Often local churchs have coffee mornings and get togethers and sometimes have people who are prepared to be supportive , whether spending a couple of hours at your house , allowing you to get shopping or get out for a walk etc. I hope some of the ideas given are of help to you.
