Luckygirl I completely agree with all the previous advice about 'going with the flow'. I realise this might seem a silly question but,,,,have you thought about getting a pet? I was injured and a friend was killed in an attack in a Middle Easter country. I had to return to the UK for treatment and although I'm pretty mobile now, my whole life has changed. My career is over and, having spent the last 15 years or so gallivanting round dodgy (but beautiful) countries, I have few close friends in the UK. As you say, it is a shock to the system - such a radical change in lifestyle and once the NHS had finished with me, I found myself feeling unwell all the time. There was no longer any reason to get out of bed or to engage with life. Yes, I got checked out - nothing wrong with me so accepted the anti-depressants and went back to bed....for about 2 years!
Out of the blue, I acquired a cat and consequently I am now a firm believer in the therapeutic value of animals. Maybe a pet might be the answer for you?? It worked wonders for me as it gave me a focus and a reason to get out of bed. More importantly, my cat was, and still is, a huge comfort and always seems to know when I'm having an off day. Please don't think I am trivialising your current situation - I just thought it might help give you a 'positive'.
