I can't write this without referring to you with you, so sorry about that
Don't be so hard on yourself. I've been watching your activity before you invested back into Steem. You've got a good heart and wanted to bring change into a system, which is not that easy to change.
Regardless if you think you've failed - I know it hurts, but those are valuable lessons learned. Don't give up now. If you need time, take a break and recharge. But life is too short to wish for its ending.
You've got a great vision. Try to surround yourself with people who are not only interested in you for Steem or Steempower reasons and are spamming anything and everything to get your attention.
Wishing you all the best,
Wolf
