I am terrible at remembeing to save fics i like, so hopefully someone here will know about the fics i am thinking of. I'm getting back into my 100/clexa faze as well.
1). This fic starts with Clarke being rescued from Azgeda were she was tortured. She is harmed mentally more than physically and i remember her having separation anxiety, but Aden worked as a good ' replacement' for lexa. clarke has panic attacks and self harms during these. Octavia and Raven are also good friends for clarke in this fic.
Edit: this fic is "To make you whole again" by TheAvidReader_SometimesWrite
2) after Mt weather clarke leaves but goes slightly coo coo. I remmeber her doing drawings in a cave using her bl**d as paint and gets an infection which lexa (and octavia and lincol) help recue and heal her. She recovers with lexa and many chapters later when going around towns get poisned (?).
If you can't tell i like clarke whump with lexa as caregivers so if you have any other fic recomendations i'll take them :D
