Yes, I did, but not for long! I tried twice via the GP and had two telephone assessments and all they did was send me info in emails. It was pretty useless, I guess I wasn't deemed to be 'bad' enough by the NHS! I then found a local counsellor on line. I saw her a few times, two or three, I think. I found it useful to 'dump' everything that had happened on someone who didn't know me, and also my feelings and concerns. This was at a time when I was struggling to accept what had happened to mum (the symptoms were very sudden and severe). I found it very helpful and by the second/third session I felt better and felt I WAS coping OK, when I'd though I wasn't. The counsellor actually told me that. I haven't seen her for ages, but it's good to know that she's there if I need her again, and she may also be able to help me through one day when mum has gone. It was £45 an hour, but well worth it.
It did feel strange going to see her as I'd never sought counselling before, I'd never needed anything like that before in my life, but with the crisis of mum's sudden change, I was looking for some support at the time, and it did help.
