Very sorry to read some of the most recent posts on here.
BLUEYESTU, you seem to have an awful lot on your plate right, a kind of tsunami of adverse life events. Anyone would find it difficult to deal with your present circumstances, I reckon. So it's important to cut yourself some slack and not be excessively self-accusatory on top of everything else.
I would also definitely have a word with your GP about what's been going on. If you can't see them personally, a telephone consultation should be possible. Perhaps an adjustment to the dosage of your medication might be required. They might also be able to prescribe a short course of something to help with the insomnia.
Moving on, the reason I am I back here and quoting myself is because I'm now doing a bit better. Not great (I'm not turning cartwheels or anything). Just better.
Many years ago I developed very severe tinnitus and became suicidal with it. What got me beyond that was taking up the practice of Mindfulness Based Cognitive Therapy (MBCT), which is a form of meditation. There's a standard 8 week programme that is described in the relevant literature.
It took me three attempts to get to the end of the eight weeks, by which time the practice has usually become established. What got me to turn the corner was that there was a moment when I began to distance myself from the habitual clusters of thoughts and emotions surrounding tinnitus, to not identify with them quite so closely or be overwhelmed by them. And from then on things got better (not the tinnitus, just my ability to manage it).
Fast forward to a year ago and the emergence of other chronic symptoms plus retirement derailed everything once again. One consequence of this is that I started to drink heavily at times.
I don't want to overstate things but in the last few weeks I have got things back on track by re-establishing a daily MBCT practice again.
Don't want to make this reply too long so I'll just state that that MBCT is not snake oil. It has been approved for clinical practice by NICE. As far as I know, the practice is not incompatible with taking SSRI's (though I never did).
It can be self-taught from a cheap paperback. So here are links to some of the best publications. I have read all of them and can couch for them.
Mindfulness and depression
Mindfulness and anxiety
Mindfulness and self-compassion (with a section on insomnia)
Any one of the above should help, though the first title is the best one.
The 8 week programme is set out in the most detail here:
My older edition looks more at chronic pain. I just applied the protocol to tinnitus. It also has a brief section on insomnia.
One last thing: I am definitely not evangelical about this approach. It's not a panacea. But I have immersed myself very deeply in the literature. The titles I have mentioned are just the tip of the iceberg.
With one or two caveats, I am personally convinced that it can be clinically effective. Plus, the method is clearly explained in inexpensive paperbacks. So you don't have to pay a counsellor or wait for 18 months on the NHS to bet to see one.
My GP is also supportive. He practises something that, in Japanese, is called 'shikantaza'. To cut to the chase, shikantaza is probably best described as a stripped down, no frills form of mindfulness.
Anyway, hope this post helps in some way.
