Speaking from personal experience: Do things you are interested in, and find hobbies. Do things because you genuinely like to do them, and don't think about ways to find friends, friends will come naturally.
As to your english speaking you WILL get used to it eventually, just make sure you practice when you're around people, and even when you're not, i found it helpful to express myself out loud more often even if i'm not around people, makes me look mental most of the time but it works, and you'd feel so much better about yourself when you're talking in public. Also, you're multilingual, most people aren't, you shouldn't feel bad if you're still picking up a new language, it's supposed to be hard, people understand that.
