Physical problems after ket abuse?

So I've been taking ket daily 1 or 2 grams for over a year now. Last couple of months it feels like theres something wrong with my blood circulation or something. Like even when I'm not high it feels like I'm about to pass out. Also my limbs keep tingling like they're numb/ falling asleep.

Today is my first day of being sober and it's hard but I try to keep myself busy. I wanted to quit before but this time it's necessary, the reason why is yesterday I was recovering from a party, and the whole time I was lying in bed and I couldn't feel my legs, like atleast when they're numb you feel a tingling/needle sensation but this time I felt nothing at all. Also yesterday when I did fall asleep though I slept for 16 hours and still felt exhausted when I woke up. I keep waking up super exhausted and totally drained even though I do sleep more than 8 hours. Also I have no appetite at all every day. I do feel hungry though and I still eat 2 meals a day because I force myself to. Also everytime I get up when sitting I feel dizzy and my vision starts to fade.

I don't have ket cramps or problems with my bladder really but nowadays it feels like my veins are empty like theyre pinched.

Does anyone else have this? What can I do?
