10 wks pp, first time mom

I have a 2 month old baby so I've been sleep deprived. One morning my baby woke me up to feed and I kept having uncontrollable thoughts. I started to panic because I didn't know what was going on. I started look around the house for someone to get the baby for me and I don't know if it was me talking in my head but I felt like I was hearing voices. After I had got a little rest and it haven't happened again but now I've been having bad anxiety and feel so depressed. I haven't been eating,(no appetite) barely get any sleep, no exercise. I have a little help but most of the time I do everything on my own. My child's father is very abusive and I just can't depend on him. I'm afraid that I may be schizophrenic or going through psychosis. I want to be here for my baby and I can't imagine anyone taking him from me. I just wish it'll get back to normal, the happy me.
