Have been awa' for a while so only just seen this thread. I'm sorry to hear you're feeling low, pompa. I am no stranger to depression or anxiety myself and have felt pretty dreadful until relatively recently. A change of medication from my psychiatrist has brought a change for the better when I believed it impossible. I don't know whether it's a temporary improvement but as anyone who suffers from depression will agree, any respite is welcome.
I have been given escitalopram, which, together with pregabalin for anxiety, is really helping my mood. If you haven't already tried an alternative I'd recommend doing that, but I might be teaching my gransnetters to suck their proverbials....
