Depression/anxiety

It's just a little rant: often I think that my problems are not problems at all, and that it's probably something I created. I'm starting to dismiss it because I don't have it as bad as others...

but how can I explain the random moods of sadness? the numb feeling? the overthinking? the fact that I hate everything about myself and my life? or the anxiety I get from having social interactions?

I haven't been professionally diagnosed because I don't have the time, and I would really like to know that I am normal and not crazy... can you imagine that? being normal...
