Losing all communication/social skills and not able to “form thoughts”

Does anyone else lose all their social skills during a depressive phase? Lose all your humor, wit, charm and conversional skills.

Like your brain is just blank during conversations. And your brain is blank in general like you don’t have a “train of thought” if that makes sense.

Also you don’t find anything emotionally appealing. I haven’t had a genuine laugh in 3 months nor felt a deep connection with anything or anyone including my own mother.

Just want extra reassurance that it’s normal to be like that and that I will eventually return normal.
