Viv,
Feeling that way isn't normal and something is definately wrong. Don't blame life......or things will get worse. Blame your health. I think JT was correct and you are depressed. I went through that crap for years and it isn't fun. Nothing excites you, everything seems pointless, and you wonder why you should exist sometimes. It's not real Viv. You are a bright good looking lady with much to live for and be happy. You have a great mum too.......that I miss here.
Please check into your health and take care of it. Perhaps some meds will help.
Hugs......
Gumby
