Many factors can be the cause of this:

You're not really free to pursue long term projects since you have to be available to work/look for a job. You are also stressed because the future is very uncertain. You do not earn money so you have to do activities that are really cheap. You are looking for a job, but a lot of that is just waiting for replies on resumes you have sent out. There is also some social isolation because of the negative stigma that comes with being unemployed.

An example: It's hard to start a business with no money, that you might have to give up next week because you might have a job then and won't have the time for it. It's not making any money yet and you need to pay the bills! You need to focus on looking for a job. Meeting the right people would help get it started, only you're socially isolated and most people are working during the week. You can't think of all that right now. Your mind is preoccupied with job and money related worries. You watch some TV while you wait for replies from companies, it's free and stops your mind from worrying.
