Anon if you do get in a really bad state such as thoughts of suicide, there are help centers that you call for help explaining your story to these people, they usually have degrees in human psychology and they are helpful .
Things that may help when you are in a rut, is go for long walk perhaps get a dog to accompany you or make for a reason for you to go for walk.
Exercise and fresh air are good for the body, mind and soul.
