Can I re-enlist with disability? Will I have to go through training, since it hasn’t been a year?

11 months ago i got a pregnancy discharge and recently decided that i want to re-enlist. I am still in the irr and i receive 80% disability for PTSD, will that be a problem? I have a code 3 so i know i need a waiver and that’s too easy. Since it hasn’t been a year will i just be able to go to a unit or do i have to do additional training? I want to keep my mos (91P). If i don’t have to do training does anyone know how long the process takes or what it consists of?
