I can't help but to feel guilty having a good work experience
Why do you feel guilty?
Because there are so many people having to suffer out there and I'm here enjoying my life.
Sometimes we have no choice about were to work if we want to be able to have food in the table, so it is good to have a job and it is okay to feel good about having a job. It is okay to feel conflicted too, so you can try to find something else while working at a place you don't like.
But I have control over what I give back to society, and I just feel like I am not giving enough at this point given how blessed I am with everything positive that I have from such an immoral job.
It's wonderful that you are able to reflect deeply into this, but the world isn't black and white. Sometimes we have to do things we don't want to in order to survive. If you're able to find a more moral job, can you try to start searching now?
