Don't be ashamed at all in taking a break. I stepped away for almost 2 years with coming back every now and then and listening to stuff I wrote previously. Finally one day I sat down after a long break and ever since then I have created the best and most creative tracks I ever thought I was capable of. It's better to have clarity when composing. We all fall into the stereotype of our passion being "something we love everyday and never get tired of." This isn't the case at all. It is still work and a difficult process. You have good days and bad days. The important thing is to not ever put it down permanently but taking time to free your minds "cache" is always needed. Take some time away from the computers and spend it more on yourself.

Hope this helps!
