Ahh you're in the UK too
Are you getting any counselling via the NHS? Must admit I gave up waiting and am paying privately for one but it's been worth it.
There are other places too to get help. There's lots of Recovery Colleges around the country. Some funded by the NHS and some are charities. They offer loads of free courses on mental health and you can often self refer. Have a google, there may be one near you.
Also if things get bad, have a look at Maytree in London. It's described as a sanctuary for the suicidal and is just that. It's a charity offering a five day stay in their beautiful house. They have trained volunteers day and night to talk/listen and some qualified psychologists to talk to as well every day. They're great at pointing you in the right direction to find more support when you leave too.
