Studying computer science

Sometimes I just feel this boredness of doing something, I use to be a smart computer science guy but now all this is just fading away. I don't know why but what I knew for sure is I loved it more than anything. I just can't live without computer. But since I became more serious about Islam and fulfilling my duties to it and become more strict, and I'm not complaining though; Alhamdulillah for the mercy Allah has given me, "Allah knows what is best for us and we do not". But my question is should I force myself to try hard to learn it back or revise, because the problem is I always feel weak and down trodden and my head sometimes aches a lot when I start learning, and especially when I'm near my book. I really don't know what to do please.
