Civil claim for my things??

So long story short I used to live at my boyfriends moms house and every single thing that I own is there. My boyfriend has moved out but his mother won’t give me any of my things the police even came to try and help me get my stuff and she wouldn’t open the door for anyone then she pressed charges for me “harassing” her??? All I did was knock on the front door and ask for my stuff I left after no one opened the door. Y’all I have nothing no underwear no clothes no computer no bathroom stuff nothing. I’m currently back living at my parents house in an empty room. I literally have NOTHING. I don’t have the money to file a civil claim to get my things back and idk what to do. I really wanted to send her a nasty message but I said this instead

Any thoughts?? What do I do I have nothing..
