My art was taken from me

3 nights ago I had decided I was going to take the bus to my local library here in Louisville. I had expressed to a few other artists that I know, that I was going to release some new songs of mine, one of which was surrounding the death of a certain rapper xxxtentacion. As I sat on the bus stop with a backpack containing a song book of newly written lyrics and a flash drive containing most of my previous recordings and all of my new recordings, a black guy say beside me. He insisted we go to the liquor store behind the bus stop to get a shot together celebrating my new songs and confidence. I agreed since the bus wouldn't be for another 30 minutes. As we sat down and did the 1 shot each we had, I really felt nothing still. I remember getting on the bus. Then all of a sudden i wake up downtown under a bridge near a costume shop called caufields. Several officers asked me if I were okay which I clearly was not. I only remember pieces but it's strange to me I only had one drink and then blacked out. Now, my idea book, lyric book and the majority of all my songs I've ever written that were placed on a flash drive have completely vanished. When I arrived home I had a black eye and scratches in several places. I awoke the next morning extremely sick, not being able to hold down water or ice chips. I spent two days like this and today is the first day I even realized that my personal items are gone. I can still write but not what I had written before about the death of rapper xxxtentacion. I feel that I was singled out and might have been talking about something I shouldn't in their opinion. If I had been "that drunk" off of one shot, those officers would have arrested me. I only wish they had not taken all of my work. That was years of my life flushed down. Please help if anyone can tell me how to better understand or retrieve my works. It was literally up to this point my life's work. I just don't understand how this could've happened. I am no lightweight drinker and one shot wouldn't have caused me to black out. Please help
