Do i need to openly talk about being bullied to move on?

No, just get over it. Almost everyone is both bullied and bullies someone at one point during their childhood/teen years. Today’s society has such a victim culture where everyone needs therapy over a little harmless name calling/teasing.

If you feel the need to get it out, there is no shame in that. Find someone you are comfortable with who will listen if you don't want to tell your friends.

It is also totally normal for bullying to have a long-term effect on a person. I have also been rebuilding my confidence for years from a series of events, including bullying that happened when I was younger. It takes time, for sure.

Don't beat yourself up for it for not having gotten over something very hurtful that happened to you two years ago. There have been things I've held onto for much longer than that, as I'm sure many of us have. Although it's definitely good to work towards getting to a point to where you no longer allow it to rule you or have a negative impact on your present, we also have to process things in our own time. In my experience, it is something that just takes time, and there's really no substitute for that. Though, that isn't to say not to try to do the best you can within that time, of course!

Per your question about bringing this up in therapy, I don't think it would hurt at all. A therapist's job is to listen to whatever you need to get off of your chest and try to find ways to help you through it.

Also, there is no shame in having been bullied. It is not your fault! I think most of us have been bullied at some point or another. It is much less shameful than having been the bully, yourself.

If I were you I would keep that stuff on a need to know basis for now, but maybe have a few sessions with a therapist. I'm glad you got rid of the friends that were jerks!

I think talking about it would help not only fully accept that it happened but overcome the embarrassment you probably feel. There is nothing wrong with venting. And you don’t need to sit down and tell everyone. For now you can take one friend to the side and say you wanted to vent out about something, then when they are ready to listen, talk. It’s going to be hard to say it but if your new friends are your true friends and genuinely care for you they would be patient and listen. And I’m glad you found better people and got rid of those toxic butthead friends you had before. That’s not an easy thing to do so congrats!

Talk to someone about it and move on otherwise your older memories will keep on bothering you.

I haven't told any of my friends that I got bullied for many years. For me because there is shame attached to it, plus I don't wanna be one of those people who whine about their bullying all the time. One of my friends know about it because he opened up to me about his early school years once, so I felt comfortable to share mine because we have very similar stories from back then. I have mentioned it in therapy, can't say it did much. Talking about something is good but it's even more important to come to a place of acceptance where you can feel what happened was crap but it's okay then let it go like my friend I mentioned who even made friends with one of his old bullies eventually. He's not bitter about anything that happened. Me I try to remind myself that those who bully usually aren't happy and are projecting. As an outsider I heard how my bullies trash talked behind each others backs and how much competition went on and how unhappy they were.
