Be careful how you approach this so you don't make yourself feel worse from their inconsideration.
Try to use other words to describe how their attitudes affect you, rather than being sick of it, or tired of hearing it or whatever other phrases are common. That's taking their bad attitudes and possible ignorance personally, internally, and can make yourself sick!
Yes, family dynamics are often some of the poorest relationships around. It could be because we expect them to know how to show their love for us, after all, they've lived with us! But often it just doesn't happen that way. They do think they know what's best for you, without asking what's really going on in your mind.
Maybe you aren't handling things as well as you could be. It's a good time to reevaluate the real situation and your responses to it. If you can change anything for your own good, then do so. If not, then what of it?
You could put them on the dime and call and ask for specific help, adding that they are "right" and you could use help handling what life has brought to you. I often have people tell me, when they see me out, that they are disappointed I haven't called (or called sooner.) I suggest that the phone works both ways (all without malice of course.)
You're stressed (((rainbowzz))) make sure the decisions you make are the best ones for you for now. Life can be tough everywhere. Do your best.
