Thank you both for your replies I think I just needed to vent I am still struggling but managed to sleep a bit last night so feeling a little better.

I think everything is just changing too fast. I really don't cope with the changing shift work and casual employment where I can be called 1/2 hour before I start work - it just makes me so tired and anxious currently - but I don't really have another option. I just need to get through the next few weeks and hopefully things will calm down, but I always struggle in the lead up to Christmas due to my past. It definitely isn't my favourite time of year!
