It's hard to cope with this sometimes

Been feeling a bit down the last few days, trying to improve my diet is hard, and managed to cut a second finger on some paper and cuts on my fingers/hands really bother me as I know diabetes impairs wound healing and things can get infected easier, also 'that time of the month' for the first time in about a year because I'm late for depo injection because I can't get one while I'm at uni as I'm not registered with a doctor here as I need to keep registered at the same one so they have all my HbA1c etc records avaible.

I do find it hard to cope with being diabetic sometimes as it won't ever go away, and it might get worse. The possiblity of going blind really scares me. I knew someone with type 2 diabetes who died last year, he had a leg amputated first and had very little feeling in his hands. To see someone go downhill that quickly is scary. He really didn't take care of himself though, he didn't even follow the standard NHS reccomended high-carb diet. But he was only about 50ish, and had been diabetic only about 10 years iirc. It worrys me because I'm 24 so it has a long time to get worse.

just managed to make myself ill eating crisps and chocolate Fridge is stocked with things that are much better for me, and that are quite nice. So I don't know why I just ate all that nasty stuff. Well it's not likely to be something I do again at least.

Yes that guy did not take care of himself at all which was probably the cause of his problems. Thanks for all the replies.
What I usually do to avoid snacking on things when watching TV etc is do cross-stitch, if it's on white fabic you need very clean hands to avoid marks on it (because you are holding it for hours and hours so it gets grubby eventually if you aren't careful), so you can't eat anything with your fingers while doing it. I suppose you could eat with cutlery but that's a bit over-the-top for a snack!
