Ive overcome lonliness in my marriage by trying to connect to support in any way possible. Usually it is a friend. Now that you are single, and having trouble with friends, I suggest going out to social events that interest you to find like minded people. This doesnt mean the bar. There is an app for meeting people for meet ups all together.. I wish I could remember the name, but its great for making friends Ive heard. For example, if you like kayaking, theres a group for it and they meet up once a month or whatever and hang together. You will find you again. It is hard at first, I am preaching to the choir but I hope this helps .
