I've been through the same and agree with the previous poster, however when you make it to the other side of the depression when you're alone, you are happier than you ever have been because you now have people who you mutually enjoy each other's company. Honestly, like a lot of things, it takes being uncomfortable for a bit to become comfortable. You won't be alone forever, unless you make no attempts to change it [be it a new job, location, bumble BFF etc.]That’s tit, I’m so sorry that happened to you. I’m going through it right now so I’m projecting my optimism.
I still have access to my toxic friend group, haven’t burned any bridges yet.
So you advise sticking with that rather than going through the emotional ringer in the hopes of finding your real friends?
Also therapy during the period or at least deep self analysis is crucial because then you can reconcile the parts of you that you have hidden shame or guilt about so that when you emerge to find new people, you are confident in what you bring to the table and 'nicer' to be around [but rooted in genuine contentment with ones self]
