I feel so so low and useless

I have lost so much recently. A good friend from high school I fucked things up with. My dream job were i made one to many mistakes and most recently, the thing that pushed me over the edge, i failed my driving test for the second time because i can't help from getting nervous even when i can do everything the test needs. i just i feel so friendless, I'm trying so hard and i keep fucking things up, i just wanna be left alone for a while, i just want things to stop. i wish i had a do over for so much. i just want to have some stability. i just want a win. i know not many people will read this but i needed to get it out there i guess.
