Hello Cat and welcome to the forums. If you have a look around I think you'll soon find that most if not all of us feel like you do from time to time. I know I do! I've been T2 since 2003 and just been put onto Byetta injections because everything went pear shaped earlier this year.
Feel free to chat, rant, or whatever you want to do. But most of all realise you're among friends. It does make life easier with us lot on your side. Take care and i look forward to gettin to know you better. XXXXX
