You can only be so strong for so long, letting the little things build and fester inside of you, until you explode. And when you do, sometimes other people get hurt too, collateral damage. You say things you don't mean and do things you know you'll regret later, but in the moment you don't care, you just need to let all of it out, let all of it escape. By the end of it, you're suddenly aware of the repercussions of what just happened and you're forced to face and clean up the mess you made.
Don't keep everything inside. Talk things out when you have the chance and when you're ready to, before it's too late. It's okay to walk away from the situation and to come back when you're thinking clearly. It's always better to be honest and open rather than let a bad situation get even worse.
I'm glad I'm doing good right now already. I've gotten rid of you in my life. Thank you for conveying the message to my colleagues that you actually do miss me. Oh, and thank you for sharing so much shit to my own blood-mum without me knowing (oh, I found out eventually.) How about you tell shit about yourself to my mum too? That'll be more interesting. May God bless you. ;)
