Succinct word for a definition [closed]

Solution 1:

I do not know in English. Depending on the context, one of these might help: self-betrayal, self-mutilation, self-scorn, self-destruction, self-denying (or the corresponding verbs).

In Romanian, "automutilare" refers to physical harm, or ("automutilare" + "emotionala") which expresses an emotional damage. We also use self-sabotage (auto-sabotare).
