T1D- Random spikes in blood sugar please help :(

Hi everyone I’m new to the group. Nice to meet you. I’m 19, and I’ve been t1d for 7 years. I haven’t ever had TOO much trouble with controlling my blood sugars. Recently though I’ve been having weird random spikes in my bs (like woke up this morning with 383, even though I checked at 2am and was 120) and it’s honestly making me feel really bad and feel like a failure. I don’t know what I’m doing wrong or what I could be forgetting to consider because this is like the 3rd time this week my blood sugar has been in the 300s. I’m trying to bring down my a1c and this is ruining any progress I had made :( Any advice would be helpful I’m ready to bawl.
