If you are alone for a long time, the loneliness will get to you, and its very possible for you to get depressed. But the good thing is, you no longer have those toxic friends, and you can go out and make some good and supportive ones. I know friends don't hang from friend-trees in friend-land, but still, get engaged in many activities, join many groups and all. You will find lots of people who are similar to you. Good luck....and for the time being,I suggest you read a good book. :)
