Its an MMORPG. You are supposed to die a lot. Its a challenge. You need to think before engaging enemies. Use the environment. If you get attacked by many, run away and fight smarter when you reengage.
You can also come back after gaining a few levels. Being 3-6 levels above enemies makes it a bit easier and you wont feel so pressured.
Good luck. Sorry for necro.
Also, make sure you have your pots and food up at all times.
