The use of stims and medpacks put me over the top. Also, learn the interrupts. They will help you in the long run. I know what it feels like to want to give up. Whenever, I got stuck somewhere I would go to the planet I was just on and level up once.

I, too, an new to this type of game. Whe I first started out, I had so many questions but seeing the rude players chatting, I started googling everything. Every question I had, I would ask it and put in SWTOR and I always got the answer. I am now lvl 41 and I am strictly playing PVE but I understand it more. I have also made it a habit of reading the forums which has also helped. The information is out there, you just have to find it.
