Severe anxiety and panic attacks. Me.

My niece is having severe panic attacks almost daily. There is no specific time when it occurs. It can occur any time. While having panic attacks, her hands and leg fingers gets bent, and she feels lump in her throat, becomes really uncontrollable and continuous crying. it is happening from 2019 and post the demise of my brother and father in 2021, the episodes are frequent. We have consulted a lot of doctors, but no one is able to help. Currently, she is under medications - Szetalo 10, Prothiaden 50 and SOS Medicine close 0.5. It is really disheartening to see such a small kid suffer like that. Kindly help I beg for your help. She is not able to perform her daily activities like going to school or any outings. We are in desperate need of help. We have no option left. Please help me.
