sorry but i just cant stand playing this game if you can help me find a way to play it that doesn't kill me form the inside i will be thankful
there are many reasons, one of then the difficulty which i find to be nothing but an annoyance
The most recent patch increased the power differential between levels - that is, adding a level adds a lot of power. So an enemy two levels above you is going to be difficult and an enemy four levels above can sometimes be impossible.
This game is an alpha release. Anything can change and probably will. If you hate it now, you can either leave specific feedback for the developers or just wait until the beta release (or the final release) when it is a lot more polished and less frustrating to play.
In the Pillars of Eternity beta, there was an infamous encounter with a group of beetles that tended to kill everybody. By the release, it was possible to win that fight - it just took some tuning by the developers, improvements to the combat feedback, bug fixing (literally, in this case) etc.
