People with mental illness usually have their own unique set of relapse symptoms. These symptoms, however, tend to be the same from episode to episode. The main cause of relapse is not enough medication. You may be able to prevent a relapse by having your mate's medication adjusted. No matter how hard you try to avoid it, you will make mistakes by saying or doing the wrong thing at the wrong time.
Mental illness is a very difficult and trying disease.
Be gentle and forgiving with yourself. If your partner is just out of the hospital, give yourself some time to adjust and time for your partner's symptoms to subside. It is normal to feel edgy during this time. If your fear is the result of your spouse's aggressive behavior, avoid confrontation and take whatever steps are necessary to ensure your safety. Take some time for yourself without your partner.
