What aspects of the game are you finding difficult?

Some general advice:

If you're still getting your head around dodging attacks, it might be worth using sorcery to give yourself some range in fights while you're still getting your head around combat mechanics.

There's a world boss in limgrave called "Tibia Marina" it drops a spirit summon that makes two skeletons. Since the skeletons can revive themselves (as long as they aren't hit when down) they can be useful to keep bosses distracted.

After you best the first boss in Raya Lucaria academy, there's an item you can give the sorcerer at the church near the start of Liurna of the Lakes. After he's left there'll be a scarab where he was. It drops Thop's Barrier ash of war. This is a really helpful ash for learning to parry, because it flashes a symbol when during parry frames so you have some visual feedback with your parry timing.

Don't be afraid to summon other players to help you. :)
