Rant about work

I spend a lot of time on work. Of so many portfolios my officemates and I oversee, there is one particular thing that will come to me on Friday and I'm required to provide feedback before Sunday noon. Sometimes when there no seating the following week, so lucky me, my boss and I get to rest for the weekend. These days, things have become worse, many other things crop out, like a text that comes on Friday night and we have to prepare the info there and then. I definitely can't have a good sleep that night if I haven't completed the job. Whether it's me taking it too seriously, these people are inconsiderate or the job is getting more complicated, I do not know. I think it starts to take a toll on me. I can't help feeling that this job is really heavy.
