I am new to this forum, but I know whatyou are going through... I suffer from Bi-polar and severe depression. First about how you feel about yourself... I know you are feeling worthless right now, but it will pass... and when it does, becaseu it will... when you are in good spirits, write down all the great things you have done in your life... post them on the refrigerator or mirror so you see how many great things you hve done. Do you know when you are nice to a stranger and smile, that can change a persons day or life? We all do great things everyday, we just can't see them when we are in this black hole. But if we have them on a piece of paper in front of us so we can see them when we are down... it helps us get out of that hole... I callit the black hole... I talk my way through it now... You have a daughter and husband that apparenty love you and support you. You are so lucky...2 people that need you and love you...
As far as work goes, I agree with so many of the others, document everything! If you can get emails or texts with any of this info in writing, it is better for you. But if you feel you are being set up to fail, 1. I would start looking for a job where you will be happy and not be treated this way. 2. Ask to speak with your Boss, and act in a manner of disbelief, like saying, " I overheard so and so speaking about.... if this is true, can we discuss this further so I can better understand how I can make things better?
Do not accuse them... they will get defensive... Otherwise go speak to your boss' boss. A boss should not be speaking to other employees about your performance. It is wrong.
I wish you the best... remember you are a wonderful person and every time you smile at someone or say something nice, you are making a difference in so many people's lives... You have mine without even knowing it... :)
