My mother has had mental issues for a very long time (just after her marriage) but after covid it increased a lot (diagnosed with covid in April'21). And the major problems which she is facing is insomnia and a different & difficult type of abusive negative nature towards everyone at home. It's not controllable and i am not able to understand if this is any kind of post-covid situation or if she is sleep deprived. We consulted with several doctors in Patna (as per them one part of Thalmas is already dead)  but it did not decrease. I really need your help here. Any suggestions will be great thing for me. Please advise.
