I routinely HATE all my new PCs. They're boring, I don't have their personality figured out, they don't have friends, and my play feels erratic and off putting. I struggle through the first three weeks, and by then I feel like I've got a handle on them and am drawn into their lives. So make sure you give yourself time to settle into your new PC before giving up again.
As you're coming back from a break, I'd suggest writing up someone with the intention of joining a clan. Any clan! It's much easier to get into the swing of a new character when you have people to play with.
