Please! Does this sound like I have adhd? Having lots of difficulty learning new things.

Probably not. Adhd is not about learning, it's about behavior. Without knowing how old you are, it's hard to say much. Adhd is not something you "catch" during adolescence or adulthood. If this problem is new, then it's not adhd. Might start by talking to your school counselor, if you're in school. If you're an adult, consult your physician.
