help with processing trauma

hihi I'm Melody!! I'm looking for all of us to process our trauma since we all very much need it. :^ I don't know what to do/where to start!!!! we can't afford any of those books unfortunately - so I kinda have to rely on help from this subreddit.. anything would be wonderful!1!1 sorry if this makes ZERO sense - this is my second time fronting, but first time talking to others, so I might not be too coherent...
