Are there any areas you're interested in that आप know other people are interested in? Sometimes if आप ask someone about themselves and their inmterests they'll start talking to आप and they'll ask आप about yourself.
I know how hard it can be to talk to new people, but आप can start with a simple "hi, how are you?" and go from there. Even if it takes a couple tries, it will slowly build your confidence and you'll get to a stage where आप can talk to people.
Just go up to people that आप think आप might have things in common with and ask them about themselves and then see where it goes from there.
I hope this helpful, and I know it can be hard but आप will get there.
Don't forget how lucky आप are to have the friend you've got. Maybe, if आप approach a person with your friend beside you, it might boost your confidence a bit as well.
And like Shepard14 said, those who are meant to be your फ्रेंड्स will come to you.
This may sound ironic, but just be yourself....People who were MEANT to be your फ्रेंड्स will come to you! Even if for a while आप only have one friend, they are the best kind of friend because they like आप for who आप are!
