Complex PTSD (C-PTSD, CPTSD)
While not officially recognized in the DSM as a discreet illness, and is described in the same section as PTSD. CPTSD does have a unique set of struggles and is considered by many medical professionals as independent.
In 2018, the World Health Organization (WHO) made the decision to include C-PTSD as its own separate diagnosis in the 11th revision of the "International Statistical Classification of Diseases and Related Health Problems" (ICD-11).
Due to this, I believe it would be helpful for this condition to have its own tag.
