Hello

I will begin with your footnote ".....it's kind of raw"
^^^^

This is nothing you should feel you have to excuse - poetry should be raw and not 'over-produced', as it were. Real art comes from real emotions - not ones that are polished for the viewing public's pleasure.

I have often spoken to people who have felt ignored by a parent or that a sibling receives far greater attention than they do (my wife is one) so I know a little of how devastating this feeling can be to the victim.
The only analysis I can offer is that - should a child feel this bad, lonely and insecure about themselves - it can only ever be the parents' fault. There is nothing wrong with you. You certainly express your feelings wonderfully.

All the very best and stay well,
Ben

Thank you - and you too.

Take care
