Thank you for the replies. I spent a couple of years trying a few ADs and I genuinely couldn't cope with the side effects, some of them were pretty terrifying.
I have been depressed since childhood and have gone through most of the motions of mental illness; anxiety, panic attacks, OCD, agoraphobia, suicidal etc and I'm at a point now where I feel absolutely nothing. I don't feel happy, or sad, or anxious, and I don't care about anyone or anything anymore. Just completely blank.
Up until I hit this wall 3 years ago, I was a relatively fit and active person with a decent job and had never been unemployed. Regardless of those things I could never shake being depressed. I went to the gym regularly and was still depressed; I got promotions etc and was still depressed; I had hobbies I did regularly and was still depressed; my diet is generally good but it made no difference.
I live by myself and don't have any family and seem to have gone through childhood to now without making a single friend, how sad is that, that I don't know any other living person? My mobile phonebook consists of the Dr, Council, dentist etc. Apart from school then work I have been living in isolation for decades and don't know how to do it differently; I can't remember not being depressed, so don't know how not to be. I've never had friends so have accepted that I'm not meant to have them. I think that's why I found much of the CBT stuff frustrating, because I don't seem to fit with any of it or can't apply myself to it as I just don't have anything else to make comparisons. I literally have nothing to be happy about (or even ok about) so when trying to think of positive things to refer back to, I can't think of one never mind the 5 the CBT suggested.
I'm stuck and don't know how to get out of it. I know it's my fault and that I can only get myself out but I have no motivation to get out of bed most days and the times I do manage, I can't wait to get back.
I've had all sorts of blood tests, and a few other things, which all came back fine. So I know it must be me and makes me feel like a fraud.
I think counselling is what I'm going to look into. I just don't know what to expect from it.
