I have had a degenerative bone condition since birth, had bad sciatica aged 5, swollen joints all my life, osteopath arthritis very prematurely. I muddled thro and got on with life. I had spinal surgery aged 23, recovered, got on with life. 6 years ago i had a terrible year and was getting chest pain, despite passing a stress test they decided to do an angiogram which was completely botched leaving me with a massive aneurysm. This was repaired but botched and needed another surgery and end result was that I was left with nerve damage and horrendous constant pain and needing a wheelchair to leave the house. It turned out the consultant had been struck off for doing the same to someone else but she died, only they let him continue operating while he a pealed. I developed post traumatic stress and it took me 5 years to start feeling even a tiny bit better. I'm now working again but get criticised that i dont sound happy enough or friendly enough when I answer the phone. I struggle with every aspect of life, I only have to answer the phone a few times a day, most of my work is face to face. I go to great lengths to help people and most customers seem happy with me but my manager expects me to grin like a moron all the time. I a serious person by nature anyway but with the pain it's hard to be so fake happy all day. I'm not grumpy rude or grouchy just not able to pretend I'm overflowing with happiness all day and my telephone voice isn't happy enough. Any advice?
