Dealing with Overwhelming Stressors: Need Advice

Hello all. I am dealing with a lot of situational stressors right now, so much that my anxiety is much higher than my meds can handle. I have finances, high bills, a lawsuit, trying to get visitation with my Grandkids, and unforseen repair bills on my one good vehicle. I have a second vehicle that is hobbling along at best and is unsafe to drive, and my sons are working on fixing my truck, but with everything else going on it is just too much. I am trying to get everything done but am also receiving flack from my wife who has suffered 6 mini-strokes and due to mood swings fusses whether things go one way or the other. I feel like I have no support from anyone around me other than the few kids that are helping me. I am also disabled so I can't just go somewhere to take a breather. Do any of you go through times like this? How do you manage stress when it seems to be attacking from every direction?
