I just relapsed

I was struggling today - a lot I hadn’t cut since feb but I had hurt myself in other ways Today I relapsed and cut after almost 9 months I’m so scared to tell my mom and older sister cause usually it ends with them being disappointed and angry and I feel like kms even more They’re supportive yes but in the moment I think because they’re worried too they get carried away I don’t know what to do anymore I did other methods of SH and they’ve all felt invalid- or like I didn’t bleed enough I hate this- I don’t wanna do anything anymore My family is already so stressed and I keep adding to it and feel like a birthday

I had my birthday in September and since then I’ve been thinking about how my birthday gift to myself was gonna be SH

Does anyone have tips on how to break this to my mom and sister ? They’re gonna see it really really soon and I’m dreading the yelling and crying

Stay safe you guys <3
