Learning the hard way...

Feeling really stressed out and upset with myself… somehow, there are just too many things on my plate and I really don’t know where to start. Whenever I decide to start on 1 thing, I end up getting chased for another thing, and this just keeps going on until I really feel like I’m losing my mind. Where should I start? Shall I just refuse them and make people upset just so I can do what I think is most important?

Yes. Just do what is most urgent and important on your list. Push back everything that is not urgent for you, even if it is urgent for others.
