Sounds like you need to prepare and upgrade a bit more. My second death (the first was a tree falling on my head) was by a Troll. I learned a couple of quick lessons - don't build a base right next to the Black Forest (or in it), don't go stomping around the Black Forest without upgrading your equipment to the max, have plenty of food on you, and run away. Whenever I get a swarm of mobs attacking me, I run and try and find a clearing to fight in. Some mobs are faster than others, so you can get them separated making it a little easier to kill them. Don't let them surround you.
Stick with it - you'll figure it out. You don't need a slider for this. Watch some YouTube videos to get some ideas - there are lots out there. Take your time. Rushing into anything in this game will get you killed. Being over prepared is a good thing. Good luck!
