I thought this was a post about how Midas screwed you over on your car or something!!
Feel free to vent, and so what if it's not life-threatening things that are making you upset. The fact is, it is
making you upset and you are entitled to your feelings. Vent away my dear!
I'm the same way when things go wrong and I stop and think, hey, it's not the end of the world, but you know what, right now it's making me upset so I just let the emotions do what they need to and then go about my life.
I have plenty of medical issues (non-life threatening) but they affect me everyday and I get upset about them because it seems like it's one thing after another and I get overwhelmed, it happens, don't feel bad for feeling how you feel. You're human.
I hope your electronics get better soon.
