What Causes Memory Loss And Confusions?

Hello, I have been having memory problems. I have never had this issue before but i feel like I forget everything and that I repeat a lot of the things that i say earlier to my friends without knowing. I cannot stay focused and have little headaches. I also feel like my speech is getting worse. Whenever i think about saying something to answer a question it end ups turning into me slurring my words or not making any sense. I get so confused and dont really know what is going on? Help me figure out what i have Please.
