I know that "normal" is an unhelpful term, but hopefully you know what I mean. I have never had serious depression as I have never had trouble getting out of bed in the morning and can always turn up to work and do my job OK. I try to get on with life no matter how bad I feel. But I think I have had some kind of very minor, low level depression for most of my life, if such a thing exists. I have never self harmed or attempted suicide but often think things like "it would be quite nice being dead, then I wouldn't have to worry about anything." I also think about how if all my family were killed in an accident, at least I would then have the option of guilt free suicide, if I wanted it.
These thoughts aren't that serious. I don't think I could ever bring myself to do it while I have close family. But I also wonder if I am a weirdo for thinking them. But I know that "normal" people have pretty strange thoughts sometimes too. I would be interested to know how common this is.
For what its worth, I am generally a pretty critical, pessimistic person who finds it hard to see the good in a situation and always sees the bad.
