Insomniac and Panic disorder. Advise!

Hello Doctors, I am writing to seek advise for my brother. He is 38 and has been taking medication for insomnia for many years. From past few years, there has been big shift in his overall personality and attitude. He is not married and unemployed. After exhausting all the family funds, he took several small loans from the banks without consulting anyone. He has been living with mother and pretty blame everyone for all the failures in life, especially mother, who has always been protective about him. He has been changing and taking medicines, not sure for what all symptoms. He also becomes violent with mother and has been constantly keeping her under pressure asking for money. He threatens her by saying that he will do something if she doesn't make the funds available for him. He doesn't want to work, but rather have very ambitious plans of doing business and also getting married, settling with kids. Nothing wrong with this, however his acts and thoughts are not aligned. Please advise
