one's limit

there are so much that you want to do but there is only that much you can do.
wanted to do well but there is a limit that i can.
the endless boundaries that people was hoping you can put it up
but there is so little that you can.

i dont know why people have expectation in me, when i don't even have it for me.
i know deep inside that i am not meant to do this, but every day i dying slowly.

i cry when i feel tired, i cry when i feel exhausted,
i cry when i feel down, i cry when i can't go on,
i speak harshly to them when they call me, i cry when the phone is off
i regretted what i did but it doesn't help.

why it is so hard? trying to just make a living??
make because of 'expectation'???
