So again, yesterday my boyfriend was supposed to text me because we were going to spend time together. I had a tight schedule that night so I was happy I could fit in sometime for my boyfriend. Well he didn't text me for an hour over the time we were supposed to be together. I was really upset he had let me down a second time. So to cool off and calm down I went on a walk by myself leaving my phone at home. When I got back I had to take care of my stuff I needed to get done. I didn't have enough time to check my phone that night. This morning when I checked my phone there was a ridiculous amount of calls and text. Not of him being upset with me but him saying he was sorry and asking me if I was okay. I understand he was worried but that's not what was the problem. He was freaking out all caps and I was only gone for 45 minutes. around 17 messages. I don't know how to feel about this. Should i be concerned about my boyfriends behavior? What are your thoughts and opinions.

Tbh I'm kind of like this. This kind of stuff happens to me when I have a depressed mood or that I let someone down. It makes me feel really bad and so I usually tend to do this, which I have gotten better at. But it still tends to happen with me, especially when I have anxiety attacks

This is normal behaviour. He was just very worried about your safety and your well being. He wasn't swearing at you, just apologizing and being very worried for you. He is a keeper, trust me. He is a person you can rely on when things get tough.
My spouse is the same from ever since we started dating. We are very happy together and I would have not been the person I am today without him.
