I find it really hard to make friends.

I have only recently been diagnosed as being on the autism spectrum. I have always struggled to make friends and not entirely understood why, but, now I have more of a understanding as to why I have always found it difficult. However, I find that I am incredibly lonely. I only have 2 or 3 friends and I very rarely get to see them. How do people make friends when they feel as if they aren't entirely understood and don't know how to interact very well?
