Jesus christ... so horrendous. The betrayal and losing those important memories and creations is going to be understandably very tough to deal with. Without dismissing your feelings though, I do wanna say this.
Things are things, and money is money. It comes and it goes in life, and you're young so you have time still to build things up, so never say never. Thankfully, you had the foresight to upload a tonne of your music to Newgrounds, so you have that at least. My grandma had a huge house fire when my dad was younger and they lost everything in the fire, maybe most sadly for me all the photographs of their memories from before I was born that I'll never get to see - young photos of my dad and such. But those memories still existed in their hearts and minds. If music is in your heart, I know you'll find a way to make it happen. I don't think you'll live your entire life without a laptop, and there's a lot that can be done with rudimentary equipment and software like Audacity.
The same goes for time; your schedule may be super busy or unpredictable now, but so much can change in a few months, let alone a few years. We'll all be here if and when you decide to be active again. I'm really sorry you had to go through this, but keep your head held high, yeah? <3

May your thief soon get what's coming to him.
