I might complain about working sometimes, but God I thank you for giving me the ability work and most importantly a job. I will never take that for granted.
At some point you'll have to disappoint others to live a life that's honest to you. People pleasing will drain you, not save you. You have every right to set boundaries and choose your peace. You can disappoint people and still be a good person
This may sound harsh, but no one likes being around someone who is always sad, always complaining, always has bad news or something negative to say. It can be incredibly exhausting.
