Need Some Rest ?

I want to keep this post simple. Do you feel like your brain is not working any more ? Because this is how I am feeling right now. I can't even think about anything. I don't know how I could write this post but umm I think I need some rest w/o my laptop and books. Writing/reading thinking even though I would like to get some vacation after leaving my job but I think my responsibilities are getting higher after leaving my job. That's not fair and white hairs on my head are getting to increase. Every day I see a new white hair and I am 23 years old. What's happening to me ? I am pressing on myself too hard ?
