Thanks for your replies.
I am seeing a councillor and have been for some time.
The PhD isn't the cause of my suicidal thoughts and attempts, however it certainly doesn't help. I want this PhD, more than anything. I have worked so damn hard and according to many academics I have Nature/Science worthy data.

However it is near impossible for me to work at the moment. I am unable write with these thoughts in my head, I'm not able to do the usual activities I do to relax (hikes, photography, fishing) because I don't trust myself to be alone, and I've lost most of my closest friends by pushing them away from me as a means to try to save them grief if the worst was to happen. Wherever I go and whatever I do, these fears follow me.

I'm sorry guys, I know this is a difficult subject and I know most of what I said is unstructured. I guess writing it down is somewhat helpful.

Hi all,

First time poster here (not a great introduction I know!)
I am a NERC funded PhD student due to finish in March. I started my PhD in late 2011 but had to take time off to look after my mum who had cancer, and also to deal with mental health issues of my own - due to this I have used up the allocated "intercalation" periods that NERC offers.

However, over the past few months I have become increasingly depressed and have made 4 attempts to end my life. I am currently seeing NHS specialists and am on suicide watch with the Crisis team, however I have refused to be admitted to hospital. At the moment it is impossible for me to work (am in the writing up stage).
I have emailed the university grad school this morning to tell them of the situation, but I really have no clue of what else to do...feeling pretty helpless.

Does anyone have any advice with regards extentions or funding that might be available to me? Any advice would truly mean a lot to me at the moment.
