Hey I was wondering how you would differentiate between pronouns.

Like when you say I like her, would it be Я люблю её?

And then if you were saying I'm speaking to him, would that be like Я говорю ему?

Cause Im trying to say "I hurt myself without thinking what was going to happen to me" and I have no clue how to put the "me"

Would these be the only cases you would use or would it depend?

Im a noob at pronouns so youll have to forgive me! Thanks A lot...Again!
