Try and find time in between things to compose, and mess around with LSDJ. I'm currently in full time education (although I'm at work experience for the next week and a half) but I also have other commitments, I've got a girlfriend, and I'm also in a non-chiptune related band. I have friends from several different circles (stoner bros, regular bros, nerd bros etc) who don't hang out together, but do hang out with me. I manage to do all that, and still have plenty of time to sit in my room for hours being hella antisocial, and staring at a screen, playing halo 4, or watching Attack on Titan. As people have said, you should make time to do it. I've done what you've done before, I used to be like that with FL Studio. For ages I wouldn't touch it because there were people out there who were so much better at it than me, or who could get the right sound out of whatever VST I was using. The problem is that you're getting too bogged down with instruments, it could be that you're focusing more on the way you want it to sound, rather than what it sounds like, if you see what I mean. Spending to much time working on an instrument to get it just right can sometimes be a bad thing, I'll often make an instrument, and go "no, that doesn't suit this, it sounds good, I'll just use this for something now, then come back to this later" and I then leave the thing that I actually made the instrument for, for ages and ages. But basically, just get it down first, then mess around with exactly how you want it to sound later.
Tl;dr
There's always time, fdon't get to caught up with instruments, not until way later on.
