Obviously, the best outcome would be for your partner to turn up to his GP and ask for help himself. However, you can still ask for help if he won't do this. If, like many people with mental health problems, he presents as "normal" when talking to someone in a position to do something helpful, you will have your work cut out.
Make a list of the things that you do for him that you wouldn't expect to have to do for an adult. These things creep up on you, almost without noticing :? :cry: You should jot down a few notes for yourself about when he last cooked for himself, when he went shopping for food, increased alcohol consumption, retail therapy sessions, problems with debt, work history, sleeping patterns etc etc These are things that help to "quantify" the problem, otherwise you end up sounding like an overanxious control freak :?
You could also make list of the effect that doing all this has on you, for example poor eating habits having an impact on your diabetes, poor sleeping patterns, anxiety, lack of time for your usual activities, loss of sense of humour, crying all the time etc etc Does any of this sound familiar?
Don't minimise the impact of doing these things - in my experience, most carers will minimise the problems. You need to be very clear about why you are ringing/visiting and tell them about the things on the lists you have written. You also need to have an idea of what you would like to happen and the consequences of inaction for example, poor diabetic control, the fact you will leave, your worries about his behaviour, your inability to work, forthcoming financial problems etc etc
You are a carer. Your partner's health has an impact you own health and wellbeing. You are also entitled to support whether or not your partner will accept help. Visit the MIND website, their information and advice for carers, and all things mental health, is excellent.
