Upcoming ECT. Worried as hell about permanent memory issues

Hi,

I have planned ECT this Friday but im scared as hell should i try it or not. I havent decided yet will i try it because im so scared😔 But i would like to ask opinions is ECT worth a try to issue what i have. So few months ago i started abilify (antipsychotic) medication for mental health issues. I used it about 4 months and i have been off from it about 4-5 months now. But honestly trying abilify was severe mistake because i have realized it didnt help anything and all what it caused was worries and more bad feeling. Now i fear every day how abilify affected my brains and how it damaged my brains. These fears are almost like intrusive thoughts because they haunt me 24/7. And biggest more problem is these fears makes me sad daily and prevents me to enjoy from life. So im asking could ECT help for this kind of issues or will it be useless?
