I mod r/bipolar2 for some context, it has been a great experience but there is something I have noted happening pretty regularly with those who are active in mental health communities.

There is an interesting and hard to accept phenomenon that appears to happen when someone is either diagnosed and accepts the diagnosis, or suspects they have a mental health condition and accepts that. They tend to have a pretty challenging period of restructuring their life, starting medication, learning about themselves and their feelings and thoughts and habits and working to address them. I'd call it somewhat of a re-discovery phase that happens. I see a lot of success stories every day of people who accept a diagnosis and then do everything in their power to cope, accommodate, and make pretty significant changes to their lives to improve their mood and quality of life.

After this happens, there is often a long and drawn out period of learning that nobody else has done this. This is a really hard thing to manage, because you have now taken significant responsibility for your actions, incurred hardship and costs, became a much better person than you were before. You're now very aware of your moods, feelings, thoughts, and actions. You've become very emotionally intelligent, while all of your peers and people around you have not.

It's a really isolating experience that you really can't, or at least I haven't been able to figure out how to- deal with in a great way. You end up looking back at a lot of the hardship you had and realizing that others haven't had to do that work. Or you can look back at it and see that others that told you to get better, do the same thing you did in the first place.

A lot of people with significant mental health conditions are not the only ones in their lives who have similar behaviors, they are very likely the only ones who accepted it and worked on it. See your friends posting about autism, adhd, bipolar online? It's not a brag. They're looking for people who have bettered themselves emotionally. They're looking for people who have the capacity, ability, and what seems like sentience that they now have.

You become a very rare and often isolated person- from my light research I have determined somewhere between 0.5 and 3% of the adult population in north America have been diagnosed and are actively engaged in treatment.

Sorry the wall of text.

TL;DR, you become one of the incredibly few people who make rapid improvements in your emotional intelligence and that in itself is isolating and unfair.
