Frustrated

I'm really frustrated today. I want to give up on all my dreams because someone said I'm the cause of our computer problems.
Last weekend, my computer froze. I told my dh the computer kept giving me notice there was no more disk space. Instead of giving me the external hard drive I'd asked for as an anniversary gift, I was told to document what all was taking up the space.
In the mean time, an automatic download crashed the system.
On Weds last week, I downloaded some work from TWRP on my dh's computer and now that's acting up. I only used the computer one day, and someone else used it pretty much non-stop til today. So, of course, it's my fault it's acting up.
Sorry if this post turned into a rant. Came back late last night from a weekend trip with my parents to CT, then working 6 hrs more than my normal 2. Getting blasted when you're tired and frazzled leaves one feeling raw.
Don't know how I'm going to finish my work for TWRP, maybe the library. Can you download PDF's on the library computer?
And how am I going to find a job if I can't use the computer? My resume wad on my dead computer, but luckily Bryant & Stratton has a current copy. I'll ask if they'll snail mail me a copy. But most companies only accept online applications. Of the twenty I've applied to in the past three to four months, there had been no responses. No one takes paper applications any more.
