Saw someone else say this, but I feel the need to as well. Love yourself. You won't always be able to please others or be what they want you to be. We all make mistakes and we learn from it. Mistakes made weeks, months, or even years ago does not call for hate or harassment.
We are simply human, we hurt and we learn. We can and will change for the better eventually, sometimes it takes the people we hurt to raise us back up. It is also up to them to forgive us when we mess up, kindness goes so far, and, for some people, it heals.
The last 2 years, I have dealt with so much, and I am finally tired. No more venting, no more talking or thinking about the things that happened or the what ifs. I aim to be 100% positive. Because right now in my current situation, despite major hiccups, I've never been happier!
