Hi Laura, welcome to the forum 🙂 Very sorry to hear you are having difficulties. One of the reasons this forum was founded was because the person who started it had been Type 1 for 35 years but had never met another Type 1. Diabetes can be a very isolating condition. The negative headlines that blame all diabetes in 'lifestyle choices' don't help people to discuss it openly, and there are so many misunderstandings and myths surrounding it.
This place, however, is full of people who know exactly what it is like to live with, and are happy to share their own experiences - both ups and downs - so you do not need to feel alone or that no-one understands.
I think we all have periods of feeling down - diabetes can amplify those feelings, and can be particularly unforgiving as erratic blood sugar levels can make us feel even worse. As you suggest, alcohol can also exacerbate things, adding an extra complication to the intricacies of trying to control your levels.
What insulin regime are you on? Do you attend all your appointments, and what sort of response do you get from your team - are they supportive?
Please feel free to let us know how you are feeling, or if you have any questions for us, there is a lot of good to be gained from sharing problems and perhaps finding solutions that others, who have experienced similar things, have found. 🙂
