It's the one where you've come out of a manic/depressive spiral and you've damaged a relationship with someone really important to you and you know you should apologize for all the things that you did but you're also so exhausted because they don't know how hard it is inside your head and you can't explain every single action you make because they probably won't understand it anyway but you miss them so so badly that the thought of not being in contact with them is suffocating? 
Or is that just me 😅
