frustrated in 2016

I have been in my new job 2 months and i feel slightly frustrated. i am expected to know what to do and how to do it. when I ask my team lead questions she doesnt make time to work with me. i dont want to say that i am being set up for failure but at the same time i feel like i am. i am trying to do the best that i can but i feel like its not enough.

when i come home matts no help and i keep getting so easily annoyed. then again he keeps leaving food on the counter even though he knows the youngest cat wont stay off the counter.

i just feel like everything is coming to a head and i want to explode.
