I need advice

What do I do with myself? The person who is most important to me in my life, I messed up. They say I almost knocked them over which I didn't know I did.

I just feel like I need to keep apologizing. I've apologized and they thanked me for the apology, they've even said their usual I love you's. We've barely hung out as much now, and I'm just super upset about it. I was caught up in the moment and wanted out of the room. Darnit darnit.

So what do I do with myself now?? I'm so dumb, and it feels like as I'm getting older, that aspect is getting worse.

Any tips/advice is appreciated. Thanks.
