I still think Fixarupa that your DH's GP needs to know how much he is suffering. I think sadly that the stigma of mental illness still exists and this is one of the reasons why people don't like seeing GPs (having it on their record) etc. Does he know that 1 in 4 people will suffer from depression and anxiety at some point in their lives, and 6 people inthe population are suffering at any one time. Almost one third of GP appts are about mental health issues, so he won't be telling the GP anything she/he has not heard many many times before.
One thing I wonder about that Hoophopes has mentioned and I have heard it said on the MH thread so many times, about going to A & E to ask to see the "duty psychiatrist." I don't know if such people exist in other Hospital Trusts but they certainly don't in mine. I had a very severe episode of depression Easter 2010 which built up very rapidly and my DP and friend were so worried about me they got me an appt with an out-of-hours GP. As it turned out he was awful, totally unsympathetic and never looked at me (I was leaning on his desk with my head in my hands saying "I just want to die" (which I certainly did) and he asked my friend if I was suicidal! He said I needed to go to A & E and should have been referred there rather than seeing him, but he wrote a note that he faxed over.
We got to A & E about 8.00 pm and after about 30 mins I was called in and a dr started asking me questions. My friend came in with me and all I could do was cry and he again he ignored me but said to my friend "how long has she been like this." Then he asked us to wait. Well we waited and waited and as time went by my anxiety lessened a little. I realised now that I was being triaged to see whether the "Crisis team" should come out. At 11.00 pm I was finally called in and seen by 2 people (man and woman) and didn't tell me who they were. One asked questions and the other took notes, and only seemed interested in my risk of suicide. Eventually I learned one was a CPN and the other a Dr. However they did say they would refer me to the conslt psychiatrist. They prescribed diazepam and sent me home. The next 2 days were a blur - a GP from mu surgery came and was lovely and gave me more diazepam and said a CPN would call to assess me later that day. However he then phoned to say that the psychiatrist was coming out to see me the following day. He did so and asked if I was willing to go into hospital, which I was and stayed for 3 months. Not made complete recovery - depression is now intermittent. I had a CPN for 12 months after discharge and he psych followed me up for 12 months too.
Sorry OP this is probably not helping you but I read so often of MNs going to A & E to ask to see "duty psychiatrist" and I honestly don't think it's that easy. Maybe it is in some areas I don't know.
Hope you can get your DH back to the GP Fixarupa but if he refuses, all you can do is help him all you can. Sometimes I just need to cry on my DPs shoulder and be held because I am so scared. I'm sure you know anxiety and depression usually go together, and anxiety is fear, so there is often a lot of fear about, and there is no specific reason for feeling afraid, other than fear of how you are feeling, if you see what I mean.
You must also look after yourself too - christmas is a bad time for many people becasue I think it tends to heighten whatever emotions we have.
