The reason you are very tired FOBD is because you are attaching expectations to all that things you do. You sent a text wanting her to respond. It did not happen so you are down.
She comes over and you are excited. She doesn't call and you are depressed.
I know it is hard.
Your emotions go from 1 to 10 very quickly.
Try to stay arund 5-6 to keep yourself from crashing so hard
