I was a very nervous person ever since childhood. But I managed to use that anxiety to do my works because it turns out being afraid of not failing can actually motivate you to like, complete your work. Great for completing homework, exam studies, and all (sarcasm intended, I was effective but totally miserable)

It has been nearly 6 months since I managed to get over these problems. I do not feel anxious about finishing my work anymore. It took months of self-CBT(journaling and exposure mostly) to get to the point I do not worry about those anymore, not regularly at least. (FINALLY)

But the thing is, now that the motivation is gone, I find it difficult to start working. I procrastinate a lot. Do things at the last moment. Without the fear, I do not feel compelled to work all day. I often drop tasks that are not crucial. Or leave them done half-heartedly. I am not the hardworking student anymore - just a lazy guy looking for the next dopamine rush.

My question is: how do I find motivation without the anxiety? How do I find a new drive in my life when I have been using anxiety to drive myself for nearly all my life? 

Any help or pointer towards book/articles/discussion forums would be appreciated. Thanks for reading this long post.
