Well my man, writer's block is no fun at all. But you're in luck, I've got the pills to cure that affliction...
Okay, not really. But I do have a couple things I do to keep myself engaged in whatever I'm writing, and I'll share them with you and see if you'd like to utilize them in your own time.
So objective one for anybody is to come up with a killer idea, something that sounds like a blast to write. Something with robots, or aliens, or armies of pygmy soldiers that steal candles from the town. Whatever you're into

. I took a look at some of the remnants of your stories on the forum and you definitely stick to the genre that interests you most. Mist was one I was particularly impressed with.
However the thing that inflicts writer's block on me in an instant is when I don't have an exact plan for where I want the story to go. These days if I'm developing a story, I'll use note-cards to write down everything I want to have happen in the story. Typically the first and last note-card are the beginning ones I jot down. It can be a quick sentence too, "Sam meets Elisia on a train in the Dome". Then the last card might say "Sam destroys the beast attacking the Dome and saves the city". After you know how you want to start and end, you've gotta keep plugging in note-cards to fill the mysterious gaps in between. Maybe Elisia runs away at one point, maybe Sam gets the Dome Police Department angry and they send a hired gun after him, maybe Sam has a gunfight with the assassin. All these can be note-cards. Just don't number them, that way you're not locking the storyline in place, you have the freedom to throw out and make new note-cards that fit better. The point is, I work a lot better when I write to accomplish what is on my note-cards. It gives me a reachable goal I can look to constantly. Might give it a try.
Another thing is if you really don't have the motivation to write anything, complete short writing challenges to force yourself back into that mood. There may be websites that can give you ideas, some of the ones I've done are like:
write a 1-3 page story in which a single character, in the first person, is stuck doing a mundane task (and the story must take place in only one scene). Or a more specific challenge like:
write a 2 page story in which a character regretfully denies a beggar spare change. It helps to have a person who can read and critique it as well. You'd need to be pretty disciplined to do challenges like this without a friend to share it with. But I find they're a lot of fun and are rewarding to complete.

I've got plenty more things that I do to stick to my writing, but I should probably get back to studying. You can PM me if you have questions or anything.
