I like the title here.
That said, the rest was a little too generalized. For example, with the lines:
'maybe someon to teach you
the bitter taste
you seem to assume that the reader knows what tears taste like. What if I've never cried? Moreover, I don't know if these are tears of joy, skin-your-knee tears, or broken-heart tears, or whatever, and I don't know what all those things taste like to you. More specifics would help... an adjective, a name for the girl, a hair color, something to characterize the poem.
Hope I've helped.

I'm thinking about being on my own
I think I been wasting my time
