Please answer...i believe im cursed and i have been diagnosed with severe anxiety?

this means the anxiety is so bad, that i do not have a normal thought process, and i also cant remember loads of my previous life. my brain is always blank. it feels impaired and cloudy. at the moment i dont have true facial expression. i cannot cry. i find it hard to smile. i am stuck in a trap. my anxiety feels more like a constant state of mind, that has just overtaken my mind. i do not worry, but my mind causes me to. i suffered worse mental health last year. the docters say i am not severly ill, and that i will recover within a year. i take venlafaxine. they should take two weeks to work, i have been on them three and i have no changes.why is this? do you think ill recover? also i feel as though im pcycotic, but i havnt been diagnosed that. its just my mind isnt what it used to be. my thoughts rarely exist, but when they do they are irrational and muddled. i feel out of touch, and cant remember who i used to be. but every day i suffer, knowing who i want and should be. i wait everyday to find it but it never happens. i find it hard to believe just 'how i will recover'. 'how does the mind know what it should return to?' i worry that ive lost my creativity, i dont see pictures i used to, or dream like i used to. is it possible that the mind can be lost? or is my real mind still there under the illness? i believe i have been being cursed. and when people say i will recover, i find it hard to believe because i think, 'because its a curse, it is the curse making them say that. but really the curse is going to make me like this forever' . is it possible i could be cursed. or is that just my irrational mind. please help me. this has been going on for five years. im now 19. and why do some people not respond to medication? please answer and try and answer all my questions by reading through again. thank you very much.
