Missed Fajr prayer on Eid and feeling really down

It's been years since I accidentally missed a prayer, seriously. Since I started taking my deen seriously, this hasn't happened. Now I'm wondering: was my Ramadan accepted if I'm starting Eid like this? I feel so terrible and upset, I'm actually crying. I set my alarm last night. Then my mom comes in right after sunrise and says, 'Aren't you going to pray?' I was like, WHAT. I grabbed my phone and it was totally switched off. It never shuts off like that-what's going on? Now I'm overthinking: Is this because of some sin? Did I somehow upset Allah? Can anyone help me calm my thoughts? I had saved my Witr for Tahajjud, so now I missed that plus my morning adhkar. Honestly, this isn't the best way to begin Eid.
