New to this and VERY confused

Hi there. So I have not actually been diagnosed with epilepsy. I don't have insurance and therefore cant afford to even see a doctor about the issues I'm having. I do not have a very good understanding of epilepsy at all, so some of my questions may seem silly and I apologize. Here's my story. I am a 22 year old female that has no medical history of epilepsy or seizures. About two years ago something changed though. Apparently I started having "seizures" while sleeping. I do not if they actually are seizures though. I NEVER remember them. Every time one has been documented it was because I was either sharing a bed with my boyfriend or a room with my sister (family vacation). Apparently I make these weird moaning and grunting noises while shaking uncontrollably. I sweat profusely also (I usually wake up soaked and even wet the bed once). My boyfriend (who has witnessed this multiple times) and my sister (who has witnessed 3 times) say that it is very hard to wake me when this is happening and that it is very scary for them to witness. My boyfriend has also reported that once after he tried to wake me I actually stood up and continued moaning then attacked him (he actually had to lock himself in the bathroom until I calmed down) after I calmed down he was able to lead me back to bed. The next morning I remembered none of this. The "sleepwalking" only happened once, but the "seizures" are happening more often. I always wake up the next morning with a massive headache and a sore body. That is the only indication I have that anything is happening at all, which even scarier for me. Is it even possible to develop epilepsy at such an age? And can you have seizures and not know it? Oh, and there is no correlation between when this started and any type of head injury. The only time I have hurt my head was four years ago when I had to get 17 stitches in my four head. Thank you to everyone/anyone who takes the time to read this and can offer any advice or clarity into the situation.
