I know the feeling - 30 years as a jw, and I'm left with just one jw who still has anything to do with me (I'm not df'd, just inactive). When you leave, they treat you like dirt and we all know how that goes.
I have made friends with a couple of people at work. But even that takes a lot of effort. Most people at work are your friends by means of work only - once the whistle blows, so to speak, it's hard to carry those friendships over to after-work activities.
The whole process is not only difficult but also humbling. Making friends often means you have to initiate over and over again. I find that to be the case, and I sometimes wonder how many actual friends I'd have if I waited for others to initiate things. And even once you make friends, you will likely still be the one who often needs to initiate.
But as the saying goes, in order to have friends, you have to BE a friend. I try to keep that in mind and find myself repeating it often.
