Option to Reconnect and Reunite with People you Once were Friends with. (Also Would Work Good for the Newest Username Changes feature)

So, I was trying to explain it to the Discord support team but unfortunately they weren't able to help me. But at least they referred me to the feedback page so this idea, maybe, one day, will be implemented.
So, long story short I had a wonderful friend here on Discord, we had an amazing communication, and one day, well, I was quite upset - things would just build up to the point of emotional havoc. And so I was talking to this friend of mine, one thing led to another and, due to the heightened emotional reaction, I misunderstood her, misinterpreted their words, and ended up unfriending her. (That was dumb of me, I know). Even moreso, I also closed the DMs. And so only after some time I realized that I screwed it up with her. I do miss her very much. I do need her back in my life, and most of all, I do owe her an apology and want to make amends with her. 
Apparently, as I learned, there's not much way to connect with the person you lost contact with on Discord. Some say if you blocked them, you can easily find them there. But we never even blocked each other - there was never a need for that - nothing was toxic in our interaction. Some others say that you can find them through the mutual server. But we never shared a mutual server. 
So, apparently that's all the options Discord currently has.
So, what I kindly propose is that, Discord Developer team, would add a little option right in the Friends window, a little feature maybe called 'Friend History' where you could see the whole list of people you were once a friends with. 

It would also perfectly align with Discord's new username update since, well, apparently it's extremely difficult to memorize someone's discriminator and if you suddenly disconnect from person, there's pretty much no way to find them back because you just don't remember their discriminator. And now you would have an option to get into Friend History and search them there and easily reconnect. 
I've read alot about some other people facing the same issue on the internet, in the reddit, and so on. Switching discriminator with unique usernames is a very good idea. But what to do those people who has lost connection with somebody they wish to reconnect with? Especially now that their discriminator will be removed and their username totally changed. That's kind of a dead-end and not a very pleasant experience in such a social networking app like Discord.

  There's gotta be a way to reconnect with the person you are no longer in contact with. After all, Discord, first of all, is a social center-hub, right? Quoting Mister Vishnevskiy: 'We were building Discord as a place to hang out with our friends while playing games. We want to make it a lot easier for you and all the new users coming to Discord to connect and hang out with friends.'
As we all know, in social environment people connect, then, sometimes, it so happens they disconnect (we all are emotional, we all can easily misunderstand and misinterpret things and we're quick to react), then, also sometimes, we feel like we have made a mistake and we wish for redemption and to reconnect with them again to continue where we left off. 
This is the typical social dynamic between humans. Whether we like it or not but this is how things work. It's a cornerstone of our relationships with each other. And not having an option to find the person once again after you lost the contact with them is kinda disruptive to this social interaction. And since Discord administration says that their initial intention for Discord was to make it a lot easier for people to connect and hang out, then it just makes a perfect sense to make it easier for people to reconnect as well since this is also a part of social interaction.

So, I would kindly ask the Discord Developer team, if they ever read this, to implement and introduce to us this wonderful opportunity to reunite with those we wish to keep in our lives. 
Thank you.
