Hey RedDot,
Welcome to PC
We hope you find what you need here!

Good job for opening up about this. The first step towards change is awareness.
Of all the friends I have know that do actions to purely seek attention, there are a few steps that they have all had to take in order to see the world and all the other people in it. First, admit that you are self absorbed. Check. That's not always easy, but you're on the right track. Next, the habit breaking. You've probably broken a habit before, and know that it sucks at first but it gets easier, and it's worth it. Your habit is your way of thinking that you seem to be stuck in about this.

One way to help you break the chains of thought could be to realize that your eyes are pointing towards the outside for a reason. If our eyes were pointing inside looking at ourselves, then we would live a very dark and pointless world where we'd be stumbling around all the time. There is no better way to lift yourself up than to lift up someone else.

And dear, I know that you know how vehemently unhealthy that is for your body, but now that you are realizing that the effects are so much more consequential, this could be a good time to start the change. Maybe it's time to forgive your body and treat it the way it has been begging you to treat it all along?

Good luck on this journey, my friend. We are here with you through it.
