What you are facing is quite understandable. You have a lot of pain and stress. The conditions which led to your sister’s problems are close to you also. Then having to deal with an attempted suicide in the one who is closer to you than anyone else on the planet, you have been dealt a double blow. Some people handle stress with alcohol or drugs. Some even try suicide, as you well know. Your stress is coming out in your sleep. Overall, it’s not as bad as it could have been, so don’t let it get you down. It has happened to many who have a lot less to deal with than you have. But both you and your sister need professional counseling to help you deal with your troubles so things don’t get worse for you. Whether or not you tell your parents about the bedwetting, you must ask them to send you for help in dealing with recent events. If you see your parents as understanding people, it will help to be open with them and tell them what is happening to you. The counselor can help you work things out in your mind. The bedwetting will almost certainly fade away as a result. (If not, you can use a bed alarm later. But first deal with your emotions.) Some parents are ashamed to admit their children have problems, and so don’t want to allow counseling. If this happens to you, go to your school officials and ask them if they can arrange for some private meetings with a counselor who deals with post-suicide recovery. That should get them going. You don’t have to tell the school anything more personal than that. Hopefully, one of these approaches will get you the help you need. Let’s get the two of you on the road to a healthier future.
