Hi Seagull97
First of all, thank you so much for sharing that with us, and I hope you'll let us support you from here with what you've been through. Both this incident and the rest of the physical abuse

It's very understandable as to how this must have effected you deeply

Things to do...........there are some things you could try when "the feelings overflow", as in breathing/calming techniques, repeating a mantra e.g. "I'm safe now", creating some "comforting" visual imagery in your mind............and things like that you'll find on here..........
But you've made an
amazing stride in talking about what happened to you, that in itself can take
so much strength, but it can also open doors to moving further forward for you........real kudos to you!!
Nothing ever makes physical abuse right.........
not the "really bad things",
not stealing cards,
not nothing and you should never have been treated that way, and
in case you've thought...........it
wasn't your fault

Now.........remember there are plenty of really caring people on here.........people who "get it"............and you're not alone

Just if/when you can, keep on talking, and keep on letting us offer you support through this.
Alison
