Domestic violence can have a huge impact on someone's self-esteem and it will certainly take time to overcome the cuts and bruises its left, both literally and figuratively speaking. The most important part for you to remember is that it IS possible to move on and regain trust in others again. Being cautious is smart and that is not "wrong thinking." But before you can open yourself up to others, you have to get some closure from your past. Talking with good friends and family always helps, as well as a therapist if you choose. Don't hide your feelings-- they're there to be expressed. And take your time. It will happen.
Okay try to do anything that will calm you down-- listen to music with your headphones, sit in a rocking chair, breathe deeply. Your body and mind are probably tired and anxious, and that's why you can't think straight. It's the adrenaline in your veins. But you can control how you feel by controlling your thoughts. Think positive. As soon as the bank opens you can go down there or call them and they'll help you sort out your credit cards. You're right-- right now, you can't do much else, so there is no point in worrying about it. Worrying doesn't prevent anything from happening. It truly is a waste of time and energy. If you can't sleep, then don't sleep. You can catch up tomorrow night when everything is sorted out.
As for your ex-- you know what he did/said and how it affected you, and that's all that matters. If other people choose not to believe you or accept it, then so be it. You know the truth. If you want professional help, then don't give up until your needs are met. How many have you tried to contact? Certainly someone will be willing to see you
Anytime. You're not ever alone! xo
