You putting this out there but not saying much. Given how people often treat others online, sometimes, i can't say i blame you.

Life is hard for some of us, more than others. Sometimes writing things in public is not the best thing to do for yourself. It lets go the wolves of this world who rejoice in other's pain. Be careful for yourself.

Be careful who you trust, for many will use your failings against you.

We all mess up sometimes. It's okay, it's life, how it is. There is not one single person out there who has not. Don't look behind you, except to learn from mistakes and try not to repeat them.

Be kind to yourself and others, it will come back to you.

I'll list my replies in the format of your paragraphs:

1.) Sometimes it hurts and you have to say something.

2.) I get that but, if I really wanted to live in this world, if I really wanted to be anything, I would know this.  Public is better, because someone else there, they will know that someone came before.  There are wolves, and I love you for having said so, but I don't have anything left to steal.

3.) See the preceding: come at me, bro.

4.) Thank you.  Thank you - thank you, and thank you again. 

5.) Be kind to yourself as well.
