No soul/dead

I can't live like this so why bother? I have no memory, no soul, no emotions, no time perception, no hunger no thirst, can't sweat, can't feel temperature, can't feel my body at all I don't exist, no opinions, no thoughts. Just been sitting here brain dead 3 years can't remember life before this. It all happened from antidepressants my gp cold turkeyed me and put me on mirtazapine and my life was over. Want to give up but I don't know what happens in the next life.
