Am I being paranoid or Am I in Danger?

It's been nearly 2 months since this happened. Me and my sister were playing with our Bokkens outside and sparring and she accidently hit the front of my head. I don't remember how hard, seeing I was in shock and scared. Afterwards I've been getting symptoms that I've never had before. I get this strain and headache on the part of my head of where I got hit. By the way, a Bokken is a hardwood Japanese sword, it emulates as a Katana. I do however get tension on my neck here and there. But it seems that the tension is all going to where I got hit, to my cheek. My Mom says she isn't worried, seeing that it's been awhile since I got nailed. But I'm not sure if it's just my anxiety or what. Other symptoms I get are dry mouth, shivering and trembling, and sometimes it feels like I'm trembling in the inside. My hands get numb whenever I get hot or anxious. Whenever I go to lay down, my legs would start to pound, like a heart beat. I do get insomnia. And honestly, I try to masturbate to see if it'll calm down. But I am not getting that sexual feeling anymore ever since I got hit, as if I have erectile dysfunction from it. Like, it takes awhile for me to get that satisfaction. Again, with the trembling, I notice the trembling in my left hand when I get anxious or hot, and I got hit on the left side of my head. I can speak properly, I am not disabled, but I always fear that there is something wrong with me. My Mom couldn't help me all because she couldn't understand me. Nobody can understand. That's what I hate about my self. With this tension on my head, it feels like it's going to split open. I do get headaches from where I got hit, and rarely I get headaches on my right side of my head. The headaches can be from where I got hit, to the top of my head. Whenever I first wake up, I feel heavy because of my head. I also get nausea, and I have breathing trouble and fatigue. I read online that that can be all from anxiety, I was never unconcious when I got hit, but my anxiety got bad when that happened, I started to have panic attacks. I notice that when I look upwards, my neck has some tension build up.Ca anybody please help me?
