It doesn't need to be.

But if you're going to have an emotional rant in which you raise questions, it's probably good to listen to the answer to those questions no matter how you feel about them. Putting feeling before thinking is how you get into these situations.

You can and have done better. This is just me pointing that out and reminding you, and also pointing out that there are people who not only expect better but know you can do better.

Not everything that makes you feel good is good for you and not everything that makes you feel bad is bad for you.
