Crying, Sadness, Pain and Despair

The feelings you get when entering a classroom after a holiday or the summer break. When you feel lost and out of touch after realizing you don't know who your friends really are since you don't hang out much with them. Also this sentence describes the feeling you get when you don't crave any physical touch but are forced to let your family kiss or hug you to not ruin everyone's mood. This is an everyday feeling that won't go away <3
