neuroleptics post-effects (Haldol)

I am a 22 y.o. white male, I was misdiagnozed with schizoaffective disorder this winter and put on strong meds this January, namely Haldol injections. I've been treated for two weeks and then received a prolonged shot of Haldol consta. Ever since I haven't felt like myself and still experiencing lot's of side-effects (or main effects) of the medication. Physical: I've always been in a good athletic form, but now my muscle mass has decreased a big deal and what's left feels very weak. I can't work out effectively anymore since I always feel some sort of pain in my body, mostly the legs, and my arms start shaking a bit, generally my aarms and legs feel disconnected and very weak. I've gained lot's of fat in just one month and I can't drop it off. I constantly feel fatigued and tired, my legs feel weak and start aching whenever I walk or stand for any prolonged period of time. I've also become virtually impotent, I don't feel any desire and my morning erections are gone. My orgasms feel very weak, my testicles have shrunk a little bit and there is very small amount of semen whenever I manage to reach an orgasm. I also experience body zaps and twitches all the time, especially when something touches my body parts, I just twitch really hard, almost jump. Emotionally I feel very numb, it feels like there is a filter between me and the world, the light and sound feel harsh to me, I can't experience joy from anything, the most scary thing is I've lost all interest in my favourite music, it just doesn't sound pleasant anymore, I don't get the chills like I used to. I can't feel any motivation for anything, as I've said I'm extremely numb and low-key all the time. Even my voice has become very quiet, a hve to force the words out. I'm very scared these things are permanent, the long-lasting shot was 2 months ago but I don't feel any improvement at all, I just want to smoke all the time although I've never been a smoker, and I don't even feel nicotine now, same goes for alcohol. I've been working out hard for the last two months, to next to no improvement, I just feel very tired and working out doesn't bring any positive emotions like it used to. I just feel frustrated because these side-effects persist and being almost impotent sucks badly. Every day I just push through the day waiting for sleep time to escape this terrible condition. I'm also afraid the drug might still be in my body since its long half-life (3 weeks, and I've heard it might take up to 5 half-lifes to clear out of the system). I don't even know if I want to live like that, a fat impotent slob. Do you thinks this is permanent, the emorional dulling, the body weakness, all this?
