I'm so tired of being a fuck-up

so, my car's windshield wiper fluid distributor seems to be on the fritz, and my check engine light is on. which means bye bye more of my emergency money..

I'm pretty sure whatever is wrong happened when I accidently went over a high sidewalk, so it's nobody's fault but mine.

Sighs, I'm seriously tired of being a fuck-up, and right now I'm struggling with feeling like everybody around me would be better off without me.
