I'm the same mate. Got no family left now. Not around here anyway. It's hard mate, it's really hard. Just got to hope it's going to get better in the end. I'm sorry my post isn't the most positive and I'm probably not the best person to respond to it but, you've got to try and keep your chin up and keep going. That's what I keep getting told anyway.
Anyway all the best mate and I hope you have the best Christmas and new year you possibly can.
This time of year magnifies these problems, my aunt died in December both my parents are gone, (my father committed suicide in a hospital on the Isle of Man with clinical depression a few years back) and My daughter had another miscarriage, i also have my wife off work for a year watching TV all day and nothing else, she is being treated with depression and this time of year i worry i am getting it,
So i have some history with this problem and how it affects all the people involved, if you ever want to PM me feel free to do so, or any other person, you know what they say a problem shared is a problem halved.
Also i would urge anybody thinking of ending it, you need to consider the people you leave behind to deal with this, it's irrational but i have been left with this 'what if ' feeling of guilt ever since, even though realistically he should have been in good hands.
