You are always changing your opinions and having mood swings. What is the matter with you? Look into the mirror and slap yourself around some. You are neglecting your loved ones, your friends, your job, your responsibilities, not to mention your appearance. So it's a shitty period, but it will pass, so get a grip and do what needs to be done. There is a bright side to everything, it just might take some work to discover what it is.
