True...
I can imagine this is not what you expected (or maybe, wanted) to hear. But I'll bet that people see good thing in you that you might not see right now.
I have (well, it needs to be re-verified and properly diagnosed) Aspergers, or Autism spectrum class something as DSM-5 now calls it. And I can relate (although other possible issues really complicate things for me), my opinion of myself is, well, let's say "harsh", but there will be people out there who care for you, know what you're going through and want to help or comfort or just be there for you. I just know that (and I'm horribly misanthropic).

Now I don't know what life's like in Denmark (and I just live 550km from the border, go figure ), but I do believe that even you can find a place where you can be understood, and learn that, yes, you are worthwhile. And yes, there's more good in you than you see right now (or admit right now).

There's proof of that even here, read the posts above and you'll see that there are people even here (this is a really good place, by the way) who can, want to, and do see that you are a good person, and you are worthwhile.

Even I care... Enough so to post parts of my experience, think thrice about what I type and how I type it. To make you feel better about yourself and see that you're not a failure...

I may be hammering my point here, and I am sorry for that if it seems this way, but I know how crushing such low self-esteem can be.
