I am happy you came back! Well, from the sounds of it, your job is incredibly stressful, and you should definitely evaluate whether this position is the right one for you. 10 years, off and on, is still an incredibly long time, but if you are getting yelled at, feeling mistreated, and being under-appreciated, it may be in your best interests to find a job that you are excited to go to every day. Work is work, but you deserve to be happy, treated with kindness and respect, and feel good about the position that you have. I know I am a sensitive person and would be devastated if I had to put up with a handful of the days you have had, so I can't imagine what you are going through.

I would meet with a therapist and talk out your options with someone. You shouldn't feel trapped; there are always choices to help make things better, even if you do want to continue working at this company. I will keep you in my prayers!
