PTSD Nightmare

Last night I had yet another PTSD Nightmare..... In the dream I was over at my moms and then after a fight her boyfriend started to hit me and abuse me all over again like when I was a child... For the rest of the dream I felt extremely upset and full of fear and my emotions felt like they were on a roller-coaster.... The moment I woke up I felt really angry.... Like I would snap at anyone if they bugged me..... Right now I'm in school sitting at the computer and as I'm typing this I feel very unusual... I feel almost sick... My head feels light and my stomach feels weak, and my body temperature seems to be acting up... I just wish I could get rid of my PTSD... it's one of the biggest problems and stresses in my life... Is there any hope for me? I need serious help or something
