I know what it feels like to have PTSD from what a person did. It wasn't a romantic relationship so I can't really understand that portion. But after I spoke out about what they did and just after I left their house, I got so paranoid they would do something to me and my family. I get paranoid something bad is going to happen to me or someone I love out of nowhere for no apparent reason. when I have these thoughts clouding up my brain, I listen to my favorite metal songs from the bands that have a really strong metal scream or accent or both. Then, I try to decipher the lyrics of the song. whether you know the song or not doesn't matter because there's always words you might not be too sure what they are. This is my FAVORITE thing to do to clear my head of thoughts similar to this because #1 you'd have loud bass, electric guitar, drums, and whatever other instruments blaring in your ears, #2 when I focus on figuring out what in the world they're saying it drowns out mostly everything else in my head so it might do the same for you. Also, if you have the kind of autism where you can't handle loud noise it might not suit you even if you have the volume low (I brought up autism because I am on the lower part of the spectrum and HATE loud noises but this isn't the kind of loud I don't like) I don't know if that's a genre you like and if it's not, there are probably other genres where you can't understand the words that you might be interested in I can look up and find some good bands and songs. if you like any kind of metal (if you want me to find something different and make a playlist with just that or both I will), I recommend this and if you want, I can make you a Spotify playlist if this interests you! I can also just find some bands/artists you might like if you give me some ideas for the kind of music you like! I'm sorry if this isn't the kind of response you wanted, I could write another one with the kind of "theme" you were looking for if that would be better for you (it may feel like I'm gonna force a response since I didn't start with it, but I have a backup that's a more "serious" way to cope in case the more "light hearted/childlike" answer isn't helpful. idk peoples ages unless they say so I try to give a response with skills people in my age group would find more helpful and if they end up being older than me and don't find "younger" tactics too helpful I just want to make sure I give you what you need)! If there's anything you need from me or need for me to do, lmk! I'm here for you brother. also, what are your pronouns? I said brother bc your profile pic looks masculine (I'm sorry for assuming I don't want you to be misgendered!!! I just want to make this more like a text from a friend so it might be more "approachable?" -idk another word, my apologies- and that's how I talk to my friends so I'm truly sorry if I misgendered you I did not mean to!!!!) so, if you don't want me calling you a masculine-presenting nickname, please, please tell me or if you don't want me to call you a nickname tell me! the things I don't want to do are upset and misgender you and make you feel bad. sorry if this last part about pronouns isn't important to you, I just want to make sure I address you as best as I can without needing your name (the way I think of it is if you want people to know your name and address you that way it would be your display name maybe). if you want me to address you a certain way I will and if you feel comfortable with telling me your pronouns, I'll use them. I don't want this to sound like I'm pushy I just want to make sure what I call you something you're comfortable with and the pronouns I use for you are correct so I can decrease the chance of upsetting you more. sorry about how long this is btw. I'm here for you through this and I'll listen to what you have to say because you, your feelings, and you finding help and joy are important to me. I wish you the absolute best of luck getting through this <3
