It sounds like it is hard to find anything to engage with others about. Only you can have interests and hobbies and thus meet others that might be interested in those things too.

My therapist taught me an important concept when she commented how animated and interested/ing I got when talking about history and what I was working on with it (mostly genealogy now). You become a magnet when you are interested in something so find something that interests you and other people will be interested in you and talking to them won't be as difficult and will be pleasurable as they will be interested in what interests you so both sides will be engaged and engaging and things will "spiral up" instead of down.
