I think it depends on the individual, really. I can speak only for myself. In general, my way to get along is to learn, to forgive, to approach things with as little bias as I can at the moment, to be stubborn / persistent / persevering at finding solutions for a) seemingly easy tasks that are frightening when you're trying to get to them b) tasks that are not at all easy at first glance but you are determined that you can and will finish. It's not a bad thing if you can feel confident and trust yourself. Sometimes a person who acts as your mentor can be a huge help. It can also be called counseling, (life) couching, a good friend's advice, etc.
My anxiety level improves when I can talk to friends and good acquaintances enough times. We discuss many interesting topics (including my special interests) and in the end I don't feel that alone. For me, friendships develop slowly, they require years to bond, but they worth it. I have to put on a bit of facade, though, and mimic the style of the communication to an extent like a chameleon, and sometimes I have to endure a bit of rudeness, but I can take it, I get more from these relationships.
