I feel so disconnected from everyone and everything and it's starting to seriously interfere with my job.
What kind of work do you do?
I work in a call center, so I have to deal with people all the time, unfortunately.
If your mental health is starting to affect your work, it is a good idea to seek help. A mental health professional can be a good person to talk to, they will help you work on your problem with disconnecting.
They all suck, seriously.
I think that's the disconnection that's talking. There really is help available, and it will help both with your job and the rest of your life if you take advantage of it.
