Whats wrong with me ? ( anxiety, panic attacks, and the unknown)

I have been diagnosed with generalized anxiety disorder, and am prescibed to a whole cocktail of medications, but it seems like they aren’t working. Everything seems to be getting worse. Before i would just have anxiety attacks, now i am having massive panic attacks and something else, but i’m not quite sure what it is. It’s almost like a panic attack because i feel like i cant breathe and i’m going to faint but i also want to break things, hurt people, and hurt myself. I know this may just be the side effects of the medicine but the problem is when i get off of the medication it starts happening much more frequently (everyday) + i have my anxiety to deal with anyways. Does anyone know what this other thing is ? I don’t really like medication but does anyone have any suggestions on what kind may help this ? I really don’t want to be on xanax anymore, i’ve only been on it for a few weeks so i doubt i’ll have benzo withdrawals. Help me figure this out !
