As my sister was having bipolar mania from Dec 2021 then we consulted with psychiatrist and given medicine(OLA10 mg,Litcha sr450,monotap 50and lorex 0.5mg) then after 2 - 3 months we were seeing she was recovered . But then in March starting she start sleeping alot , become so sluggish and lazy not eating food and not doing anything only sleep a lot . Then we consulted doctor he told that she is in depression and given medicine (Litcha Sr 450 , OLA 10 and lorex again ). Then after few days she was normal like before she was energetic and eating food . By mischance she didn't  eaten medicine as she was out of station and we thought she is taking medicine But she didn't  take those for more than 10 days . Then again from past 3 days she is behaving like earlier so much sluggish and sleeping more than 15 hours . Not eating food but we are forcing her to take little and take medicine Also she rudely told our mother that don't talk to me for 7 days do your own work.Please help what to do.
