Getting past baggage can be both impossible and stupidly easy all at the same time.
The thing about trauma baggage is that you carry it around partly as a coping mechanism. You brain says "no! You can't let this happen again! You have to remember! You have to do these things! You have to be safe!"
As you work through the healing process you start to unpack those bags and they get lighter and lighter. But you have to deal with them every day and the change is so slow that you don't notice. You just keep thinking "these bags are so heavy and they make me miserable. I hate carrying them."
Eventually you hit a point where the bags are unpacked. Everything has been handled. You are, effectively healed. You have scars, true, but you're recovered. The problem is that by this point carrying those bags is a habit. Your brain thinks you need them. You've defined yourself by these bags for so long that it feels like they're a part of you. You've defined yourself as a victim of trauma and made those bags part of your identity.
The very last step in healing is to put the bags away in the closet and recognize that you don't need to drag them around anymore. They should no longer define you, and you no longer want them to.
Some people never figure this out. They spend their entire life collecting luggage to drag around with them, because it's who they decided to be.
Some people learn to do it through therapy. They practice putting the bags down and going out for the day without them. One day they realize that they haven't picked the bags up in a month.
And some people are like OP. Something happens in their life, and they take stock of themselves. And then they see that they've been dragging around an empty bag that they no longer need. So they just set it down and abandon it.
You can't get rid of baggage until it's empty. It will absolutely crop up if you don't deal with it. But if you have actually dealt with it, it can be the easiest thing in the world to toss the empty bag. The tricky part is recognizing that it's empty and you don't need it anymore.
