Need someone to motivate me to continue studying

I started studying Japanese after i got back from a tour of Japan this year in June. I absolutely adored learning and I was having a blast. I studied it with a textbook call Japanese From 0! and got all the way up to chapter 12 and just suddenly lost interest when school started. Every since August I have not studied but I still remember every hiragana character and some rules of the particles, but not all. I'm starting to think that my biggest push to stop was that i kept getting unmotivated because I just can't remember any vocabulary whatsoever. Someone please help motivate me to want to start studying Japanese again because I've tried to motivate myself and I just don't do a great job at that.
