Nobody's perfect, and no matter the outside appearence, everyone has their problems. I can honestly say I do not know anyone who functions perfectly, even people who appear "normal" tend to have something going on 'behind the scenes'. Often when you go to people's houses, they have tidied because you are coming round, and often people will act happy - it doesn't mean they are: as they say, don't judge a book by it's cover. Nothing you've mentioned makes you a failure, and I'll bet that if you wanted to you could make a decent list of your life achievements.
Have a virtual cookie (or something else if you don't like cookies, it being virtual it's flexible lol).
*VIRTUAL COOKIE/INSERT ITEM HERE* Good luck feeling better!
