yes, I second what was previously said, I definitely agree with Xando and Open Eyes. my situation is somewhat similar, although it has calmed down tremendously, but there were times when I didn't think I could go on. I will pray for you and your parents, please please please don't give up
things will get better even if it doesn't seem like it right now, don't try to figure out every thing right now, just get through the next minute, then the next....and as far as seeing the positive, if there is one little thing that makes you happy, like the thought of the puppies chewing on your shirt (I love that!!) or whatever the thought might be, meditate on that all you can.
