My partner has Type 1 and has done for some time. Over past year I've noticed a massive change in his mood which I'm certain is due to his diabetes, he's not eating properly, in my opinion isn't hydrated enough (one or two coffee's then just beer for the day). He's got a real lack of motivation to help out, I end up nagging him to shower (it can be up to the best part of two weeks!) he's snappy and aggressive but doesn't seem to notice, even if I point it out. I'm trying to be supportive but it's so difficult. He even accuses me of finding his condition a massive joke, I'm near the end of what I can take now, too worn down to be supportive and to afraid of his moods to speak up. It's now got to the point of he spent yesterday having a quiet day at home as his eyes are bad, I had a manic day and said 'wish I could have a quiet one'. That was it, everything's a joke to me, I'm cheating on him in his eyes. He doesn't want me going to see the surgeon with him tomorrow. What am I meant to do?!
