I was going to say exactly what Cherokee posted ... think it is brilliant that you have made the first step to recovery, in other words you have 'come out' and admitted to yourself and 100's of people on here that you are suffering from depression of whatever kind !! Well Done ...
'Course you realise now that there is no hiding and we will expect updates on your progress, and we do all mean well on our advice and anecdotes of our own similar experiences.
No blooming wonder yer self-esteem is low ... split up with wife; losing your business; house removing ... all the three big 'S's' stresses !! You have no reason to search your soul to ask 'Why me?' ... hope I am not sounding patronising.
Was musing a little tonight, and do get metaphoric at times ..
Nearly came and joined you in that room tonight, as put on a hair colour that is too dark for me ... need a paper bag ...hey, but it is semi permanent, will lighten up every day at each wash, and eventually get back to my natural colour (which is pretty good still actually). I thought this is hopefully what will happen to TJH, with professional help ... and he will get back to being his natural self, and look in the mirror soon and think "Hey, I'm Great !" I am confident this will be the case because, as you said, you have made your 1st (well, I say 2nd) positive step to getting better.
