Yes - and the mini-disasters always seem to come in threes for us! So if two things blow up, I'm bracing for the 3rd. I definitely go through times when I feel like you. I want to yell "why me?" or say "are you kidding me how is this happening" and go back to bed.
The reality is that we all deal with this kind of stuff all the time - you're right, it is just part of being an adult. And if all you had to worry about was what to wear or have for dinner, I bet your life would feel pretty empty. The first thing you can change is how you react - don't think of these things are potentially "ruining" your good streak, just think of them as expected and manageable bumps in the road and be glad that you CAN handle them. Our fridge stopped working this week. It was a $265 repair and we of course didn't budget for that, but at the end of the day it's not literally breaking our bank. And I'm glad that we don't have to replace the fridge. And somewhere, someone in the world would be happy to even have a fridge, so it's a privileged problem to have. And we got it repaired quickly. So really, more to be grateful for than annoyed about.
Some other things that you can do are to take care of your health - if you find that you're feeling pessimistic and are dealing with weight gain and fatigue, you could have a fixable medical problem. So address that. If you're feeling well mentally and physically, you can let things roll of your back.
The other thing is to take steps to get control of your finances so that you have emergency savings. We definitely don't have months and months of salary saved like people recommend but we usually have $1000-$2000 available to pay for unexpected expenses. We just blew through a good chunk of that repairing one car and replacing another, but it takes so much stress off of your shoulders to know that you can handle something smallish.
Finally - and I know that this may sound awful and I hope it doesn't - I think of the people I know who have medical issues. Unfortunately, I know one family with a severely ill and disabled 3-year-old. They literally have a pediatric ICU in their house. He needs a vent, G tube, J tube, is paralyzed and has cerebral palsy. Another family I know has a son - also 3 - with mitochondrial disease. He looks healthy today but needs oxygen and a feeding tube. He is hospitalized several times a year, and his mom posts every few months on facebook a prayer request for yet another mito family they know whose child has died. I've never had the guts to ask what his prognosis is, but kids like him usually don't survive childhood. An acquaintance died of cancer on Monday after a 7 year battle from hell. And on, and on, and on. I know that for these families, dealing with a crashed car or a dead transmission or a warm fridge or a backed up septic system, or even a job loss or a custody battle (all things that have happened to us in the past 6 months) would be a walk in the park compared to dealing with illness. So it's about perspective.
I hope your cloud lifts and you feel more optimistic soon!
