Tonight I was supposed to go over to my boyfriend's house. Today is the day I usually go over. We were messaging eachother around 8 pm when he suddenly stopped responding for a long time. (The reality??? He just fell asleep for 8 hours). But in my head, these are the intrusive thoughts I was dealing with: 
"Oh god, it's already been three hours since he replied. And now im seeing that he deleted his Twitter? Oh god, this could only mean two things. 1. He's mad at me for some unknown reason and is shutting me out
Or 2. He killed himself. Yep. Omg he probably killed himself. Why else wouldn't he respond for 3 hours when I'm supposed to come over? And why else would he delete his Twitter?"
*Cue severe anxiety/pit in my stomach for the next 8 hours. Cue me frantically thinking what Im supposed to do without him in my life*
Now, 8 hours later, he woke up finally and finally responded. It was an immediate relief when he responded. "Ok, good. He's alive and he isn't mad at me. I can relax now."
