This is so something that I have done before, and the best thing to do is explain why. Tell them it’s not personal, and you have been withdrawing from social contact in general.
HELP; I HAVE THIS PERSON I'M MESSAGING BUT I'VE BEEN GOING THROUGH A ROUGH PATCH WITH HUMAN CONTACT IN GENERAL AND MY ONLY TRAUMA RESPONSE SEEMS TO BE DROPPING OFF THE FACE OF THE EARTH SO I HAVEN'T MESSENGED THEM BACK FOR A WEEK AND NOW I DON'T KNOW HOW TO APOLOGIZE AND I KINDA HOPE THEY SEE THIS SO I CAN SKIP THE ODD CONVERSATION
