For one thing, having this panel would be educational for younger audiences - the teenagers who think that guys who are possessive, stalker-ish or talk smack to them are 'romantic', the Twilight generation - and help them recognize unhealthy relationships.
And, it'll teach them how important consent is.
But, I'm also confused as to what you really want out of this panel... 
Could you tell me what your goal is?
Goals:
The first goal is actually for myself. I want to do something that will help me get over something and help me heal a little. By doing this, I am having to read a lot of yaoi manga (which I once enjoyed in ALL forms but now can only find a small bit of it palitable. It is a huge change from my former self)
Second goal: I want to let people know there are options. There are yaoi manga out there with relationships that don't involve sexual harassment or non-consent. Also there is yaoi manga that takes consent more seriously.
Third goal: To help others who want yaoi manga like this actually be able to find it without digging through a mountain in order to try to find it.
Fourth goal: To create awareness. I think a lot of what is in yaoi manga can be problematic. I know when I was 12/13 and being first exposed to it, I really didn't see anything wrong in the media I was watching/reading. And I continued to be oblivious until bad things started happening to me... as an adult...
Those are really the main ones.
And I think having a all ages panel would be great to discuss relationships that happen in our manga/anime that aren't healthy. But I have no idea how to run with that. But I would be happy to help with one if someone wanted . Manga/Anime off the top of my head that fall into that are Sailor Moon, Card Capture Sakura, Gravitation, Yugioh (unhealthy friendship between Yugi and Seto Kaiba), and for something that isn't anime you have My Little Pony and the Episode where Fluttershy was asked to watch over Discord and he treated her like garbage but through the power of kindness and her letting him abuse her, he became reformed. It was a really terrible message.
Wow... Did not realize I could do a chibi version of this.
Ah, I see now, thank you for clearing that up for me.
From what I understand, you want to spread awareness of how sometimes unhealthy relationship are portrayed in some Japanese content (Anime, Manga or Doujinshi); and, you want to offer options that incorporate healthy relationships. And, maybe, doing this will bring you some closure - right?
I think this is a nice idea; and if you're comfortable doing it, then give it a try.
I sometimes struggle with finding new manga and anime to enjoy. I used to read a lot of shojo manga while I was in high school (and sometimes I still read a little bit) and I thought they were relatable and it got me through some tough times. But, after all these years, I've picked up a few that look good at first (I read about fifteen sample pages before deciding to buy it) and I realize that they portray unhealthy relationships and always put the girl in a bad spot that, really, young girls shouldn't be reading about (like Peach Girl or Stepping On Roses).
It makes the feminist in me seethe, really.
It would be nice if there were lists that showed manga/anime that empowers people, shows healthy developmental growth and portrays how relationships should be - or, show how to
get out of bad relationships. But, sadly, the media seems to think that the younger generation likes to entertain themselves with content that shows women (and men) in helpless situations and be pinned as a victim.
I do have a few things that I would like to mention that might help you get started and help organize your plan: -If you're going to host a panel and would like to make it available for all ages, you will need to avoid using foul language and avoid showing anything that has nudity or sexual content - otherwise, it'll have to be an 18+ panel.
-Do make a list of manga, anime or doujinshi that portrays consent and healthy/acceptable behavior in relationships and talk about them; this will give the audience choices and it might even be thought-provoking if they decide to look them up and give them a try.
-If you're comfortable with this, feel free to provide key information that points out the warning signs and red flags in an abusive relationship.
(Examples: Your lover isolates you, hits you, talks down to you, checks your phone and wants to know where you are constantly)
And, provide information on where to get help.
And, on a personal note, I'm very sorry for what happened to you.
