I'm feeling really down

Wish I lived a bit closer, that cafe sounds fab and by the smile on your photo I think we'd have a good laugh! So pleased your day improved

First put your situation into perspective. You could be waking up daily to worse than 7 mmol/l. For a long time anything less than 15 mmol/l used to be a good day for me. If you are finding it hard to motivate yourself then see your GP if you think you have metabolic problems that can cause lethargy (probably your diabetes is making you fatigued) or clinical depression. I took antidepressants for years and no longer take them but they did improve my thinking and did their job. Try and seek help, nothing worse than being in a rut.

I did try some antidepressants but did not think they mixed well with my diabetes tablets as my stomouch was terrible and would wake me up in the night with terrible pain soon as I stopped taking them it was fine again

I really struggled at the thought of giving up lots of favourite foods but it has become second nature now and I don't even think about it anymore. Things taste great and I can eat many foods I have spent my life avoiding, like cheese and cream, nuts and cooking with olive oils, food tastes richer. I looked at receipies to make low carb versions of some favourite foods and you know what, I like some of them even more than my old favourites. You sounds as if you gave already done the hard work and decided to make changes, and you are already seeing the benefits and more will come, just give it time.
This weekend, I went away with my husband, a few months ago I struggled with food on the go but with a bit of planning went armed with chicken portions with a dip, nuts, cheese and my flax seed crackers, and a bit of 85% dark chocolate, I had a feast. The hotel breakfast buffet provided natural yogurt with berries, bacon, sausages, eggs, tomatoes, cheeses, smoked salmon..........I was full, low carb does not need to be boring!
Good luck, everyone here has helped me so much over the past few months and we are all here to support each other. I am sure you will be fine. You are doing great!
