When something else bad happens, adding to your anger

There has to be a word out there that describes the anger, stress, and frustration that piles on you when something else bad happens when you're already dealing with something very bad that happened before that. It's enough to drive me completely insane at times!

Let X and Y be events that, by themselves, will make you angry. Suppose X happens and it makes you angry. While you're still dealing with the anger from X, Y happens. Now this makes me 1000 times more pissed than if either X or Y happened or even if X and Y happened simultaneously!!!!

Example 1 (this is what I'm venting): My 2TB external hard drive failed... well not completely but it seems the connectors to it were toast. I panicked before I found out the drive and my data (like all my photos in the last 10 years with no backups) on it were still supposedly OK. This was last night after all the computer stores were closed. Fast forward to today, I had to work all day and could slip by the computer store an hour before it closed. I bought a new external hard drive case with new connectors to hopefully revive my old external hard drive. Turns out, the screws on that case were so tight that there was no humanly possible way to remove them (despite strugglling for 2 hours this evening when the computer store was also closed and I had to wait another day to return them.)

TLDR version: Hard drive broke, and I can't access the data on it. I go to the computer store and buy the part that'll make my hard drive work again but the stupid screws on it were so tight I can't loosen them, making that part effectively useless and I have to wait another day to get my HD (with all my data in the last 10 years) working again!!!!!

Example 2 (Hypothetical example): If the previous example didn't make any sense, then think of this one. You get into a car accident because someone decided to run a red light. The SAME day when you finally get home, and are dealing with the frustrations and anger from the car accident, lightning strikes your house, setting it on fire. You're 1 million times angrier than before I'd imagine.
