I'm sorry that you have so many things to deal with and the people around you are not being very helpful. On the other hand, it sounds like you have risen to the task and handled it, so good for you for dealing with all these obstacles. If you can make it through a day like this and not fall into pieces, there's not much you can't do. Go ahead and vent. That's what we're here for!
Hugs,
Wendy
