sometimes my medications make me feel this way. when that happens my treatment providers do not call it depersonalization either because of the new standards in the DSM 5, medication causes have to now be ruled out.

suggestion if you are on medications like welbutrin or other antidepressants, anti anxiety, antic psychotics, benzo's and others like these maybe you can talk with your treatment providers, they can adjust/change your meds so that you dont have this side effect any more. it really helped to stabilize this problem for me when my meds were adjusted/changed.
