Fell asleep through date night

I was supposed to go pick my man up, and I fell asleep and none of my alarms or phone calls woke me up. He was obviously worried and I just woke up and I feel like the shittiest piece of garbage on planet earth. They were new plans and he was so excited to go see Infinity War and I can’t believe I stayed asleep the entire time. This week has been particularly stressful and I haven’t been sleeping much and it all hit me at once.

I’ve sent him a million messages explaining and apologizing but I feel so guilty and I can’t stop crying thinking that he was waiting for me to respond all night.

Have any of you ever done any of this? I don’t know how to cope with the feeling of having done that to somebody
