My advice is to look at forming friendships as a rather cold-blooded exercise. If you spot a person who you think may have the potential to be a friend, then invest yourself in an ongoing effort to give that person the support that they themselves are looking to have from a friend. Whatever psychological boost they need to get from you - give it to them. Keep doing this day after day after day.

However, do not expect them to instantly be a good supportive friend to you, because they won't be. You'll need to put in a lot more to the friendship for a long time then you'll be getting back. Most people are innately selfish. That's just the way it works. But use their selfishness to your advantage. Give them what they want and eventually they'll come to realize just how much they enjoy your company.

Once you have become valuable to them, then they will work a little harder to become a good friend to you.

Some day, this could evolve into a truly beautiful friendship. But you'll have to do all the heavy lifting in the beginning.
