I'm sorry if this is not a good post for this thread. My sister is currently suffering from anxiety, and I try really hard to be supportive, which is hard sometimes, simply because I don't feel that there is much I can do except be there for her and be understanding and never stigmatize. I've never directly suffered from it, so I really try to research and understand so that I don't make mistakes by trying to support her in counterproductive ways. 

I'm just struggling because sometimes she asks favors from me, like taking taks off her, or even doing a minor homework, and she usually cites the anxiety as a reason why she's asking. When she does, I really feel compelled to help her, and usually do, but I sometimes question (and feel bad for questioning) if she's using the anxiety as an excuse to avoid taks that don't really have much to do with the anxiety.

I guess I came here to get some insight on whether you think I'm doing the right thing by helping her, or if this might actually do the opposite for her. Since I've never personally felt it, I don't know where anxiety stops being a valid excuse (if it does), and I don't want to end up affecting her more than helping her. But overall I do want to help her as much as I can. I'll really appreciate it if you have some personal insight on this.
