This is something all capsuleers struggle with – newbies and veteran alike – but for different reasons. Attitude & determination go a long way in this game.
My recommendation is: if you ever feel this way, pause and reflect. Figure out why, figure out the things you have the power to change, and make that change. You’ll go a long way.
More concretely, I second ISD Drew’s recommendation of the Novice Frigates Yearbook. But note a few things:
Its “Novice” in the title is a reference to “Novice FW Plexes”, which limits the kind of ships inside to those in this guide. It is not a reference to “novice/newbie capsuleers”, as the guide is good for capsuleers young and tenured alike. Note that – due to the guide’s age and your hard-skills – some fits don’t exactly work exactly as described, and will require tinkering.
The guide is comprehensive, but intimidating. There’s only so much that sticks by reading. So I also second Gix’s recommendation: get into as many fights as you can early on. At first you might get the “PvP Shakes”. Even without those, mistakes will be made. Reflect, Learn, Do, Repeat. Eventually, you’ll learn when you don’t want to take fights, too.
FW Corps help, but don’t feel pressured to join one right away. Each group has a different feel, playstyle, fleet style. It’s OK to join the regular militia, socialize with your fellow militia-at-arms, and get a sense of which groups you like better. Talk to your allies, get into trouble together.
Pick a path, if you don’t like it, pick a new direction. Yesterday was the best time, but today will also be OK. Join a militia!
