You can't handle it, because it's too much.
You're stressing about a lot of stuff you can't control and the worst part of that is that YOU can't just magically stop stressing about that stuff. If you tried to stop stressing about it all on your own, then you'd just be adding to list of stuff you need to stress out about (am I stressing about this? Oh no! I am <stressssss>).
I wish I had a great answer to all this, other than the one that as a Christian I am positive you already know.
I can sympathize. I spent last week in a funk, trying to explain that when I say "I am just not motivated" it doesn't mean anything against anyone, it just means that... I am just not motivated. I *did* make it to church Sunday and it made me feel.......... better and worse. Better, because I can see the light breaking through the clouds; worse, because in my case a lot of my problem was that I had cut out studying God's Word and praying.
More hugs, sweet lady. I really wish I could tell you some wonderful thing that would fix it all, other than the oft used answer, spend some time with the Lord. Stressing about stress isn't going to help, stressing about trying to not stress about stressful things that you can't control isn't going to help either.
