serious about something

Today marked my 1 month point at work at RITE AID and they will keep me on for 1 more week to see if i can improve. I do not see how i can, when they tell me what i am doing wrong then say nothing on how to improve adjust or correct myself. which makes it that much more frustrating, especially when i almost broke down and cried (yes i will admit it) because i felt like i had been stabbed in the back. everyone else there just watches and they do not try to help and i start messing up or doing things incorrectly because i have no idea what i need to do or what is going on, then when i try to get help they say i am handing it off and saying "you do it." what is going on there is something came up that i need help with and there is not much i can do about it and now i am the bad guy cause i do not know what to do cause they wont let me know what do to?!?So what i am going to do is take everything my store manager told me do the best i can to meet her expectations and i will do with a S.M.I.L.E. and if by chance next week comes by and i am let go . . .in that case i shall also let go and i will hold no hard feelings towards anybody(except for myself)
