Yes, unfortunately I can relate.
Most people at work think I've got something medically wrong with me. If they ask I just say I'm ok.
My closer coworkers know "something" is wrong in my personal life but I haven't shared details. they offered their help which I really appreciate but don't wish to share all the details.
One close friend at work knows everything and she has been great. She is acting as a cover for me and telling people I just have a lot going on but will be okay.
The other, opposite issue I've encountered is people telling me how "nice" I look because I've lost weight.
They ask what "my secret diet" is and I just tell them exercise and healthy food. I know that's a bit of a white lie but I guess exercise class 4x week + no food is kinda the truth. I sometimes just say thanks but it tears me up inside. They have no clue what price I've paid.
I've lost 25+lbs since June and gone down to a size 6. Sounds great except I don't feel great.
I went for a mani/pedi for the first time in years last week and that "good" feeling lasted about 2 days. After that I was back to feeling blah again. Unfortunately I can't afford more of them.
Searching for other things for that 'feel good' feeling is very challenging but I do try.
