This poem seems to be advice to a young woman from one who has been there. Your mood, balanced between irony and bitterness, is difficult to maintain, but you accomplish it beautifully.
Your truth is certain: pain doesn't stop because you want it to. It must work through the system entirely.

Your final stanza crowns your wisdom:

"Maybe then
you will find something substantial
enough to ease the pain
and hide the scars that
only appear in the light"

These words can only have come from one who has weathered through.

This poem is very touching for those who are in need of hearing this. The mind is such a complex thing and we often fail to see the truth that is in front of us because we choose to focus on the lie that we create for the future. That things will get better and change. When in reality they won't.

Great work x
