Is it normal if you can't remember anything?

I mean I think it is normal to have a bad short-term memory or long-term memory but for me its like both. I also think I have a learning disability. I can study for hrs (even tho I never did ef that) and focus really hard ace that test or whatever. Then its all gone. It gets even worse. I graduated but to be honest, I feel no different. Yeah I learned big, broad things but stuff that I know I went over so many times, I have to go back and learn it all over again. Or like small items like addresses, phone numbers, it will take A LOT to remember that. Also events, moments, etc. So when I'm entering data at work, I look dumb cause I forgot something that I was just given to a second ago as if I'm not paying attention or I'm slow. Everything is a challenge for me basically because I feel like I have to learn it all over again at the moment. Mentally challenged? Idk. Learning disability? I wanna say yes. So what can you do in my case? Especially for a job/career if I have a serious memory problem/learning disability/possibly mentally challenged? My ultimate dream career is to be an entertainment reporter. I love entertainment and I think it's fun. But it is news and I feel like I'll mess up delivering news by delivering something I just said, or looking like I don't know something but it's because I don't remember it.
