This morning has been horrible. I feel so bad. I wonder if it's the minocycline (Acne med) I started yesterday.

"Individual case studies also point to a possible link between minocycline and negative mental health effects.

In one 2019 case reportTrusted Source, a 37-year-old woman taking minocycline for a skin condition began experiencing symptoms of depersonalization 2 days after starting the medication. She also reported a loss of interest in things she’d usually consider important, another symptom of depression.

She had no personal or family history of any psychiatric condition — and her symptoms improved within just a few days of stopping minocycline."
