Hi Mrs P, so sorry for you losses, you have had a rough time over the last 8 months and I am not at all suprised that your haven't been looking after yourself, but I am glad your have decided to come back to the forum and seek advice to get yourself back on track.
I see from you previous posts back in March that your received the advice from Daisy1 regarding cutting carbs from your diet. Also if you google low carb smoothies there are lots of websites with receipes which you can make yourself.
If you need any more information, please ask.
All the best
Marilyn
