You can't continue without any support, through whatever means you need to see either the crisis team or get regular appointments set up with someone from the CMHT. I would imagine your GP is the best person to push for this, failing that you or your partner will need to contact the CMHT and explain how distressed you currently are, get nasty if need be. If you still get nowhere you can contact PALS
http://www.pals.nhs.uk/ they are very good and can often 'push' where others can't.
If you are feeling down but don't feel like going to A&E you can always ring the Samaritans 08457 90 90 90, it can help to clear your head to a complete stranger.
When are you due to see your GP next? If you aren't well enough to be at work would they give you a sick note? Even just for a week or two to give you some rest and take some stress away.
You're welcome, PM me if you like xx
