Should I start new?

I found some items and all sapphires missing today and also found a log in my parent Account of a login at 5 pm PST -> 2 am in my time Zone, so really not me. Probably hacked by someone. Its sad but the Support wont help how people told. I am just Level 10 and the only thing that would be hard to get would be the my Shop because you need 100 sapphires. The most nice stuff I got where gifts from some friends and people on here I didnt trade so I dont even know how they thought I would have something to get. Should I just start new or try to continue with the items I have left (one alpha item, maybe the number is to recognizable -> just made Screenshot, if someones gone take it from me I will find it again)?
