Hacked, should I quit?

Well I was away for a week, and when I came back home, I discovered that I had been hacked. This is what I lost, 96 attack 13 luck Maple Dark Mate, 12 luck 2 attack Pac, 10 attack 2 luck purple wgs, 86 attack clean kebob. My dagger was my motivation to actually play and level, and now it's gone. Well, I have 270m on my mule, so I still have that. Idk if I should just quit or start all over with that 270m. I kind of feel like quitting because I've worked hard to get all of those items, and now they are gone. But, I also feel like playing because I'm almost level 70, and I've never reached 3rd job. People have told me I can merchant with that 270m and buy all those items back.

What would you do in my situation?
How much would it cost to get all my equips back?
Please let me know if you see a dark mate, 96 attack 13 luck. It's +4 in purple text. (Windia)

Thanks everyone.
