Hi kubali and welcome,
its quite possible that you have ptsd considering the things you have been through - usually you have flashbacks, anxiety, nightmares, hypervigilence, depression, a loss of the sense of "safe" - there are many and varied symptoms but these are the ones that come to mind .
I am sorry that you had to go through these things and hope that your current relationship is better and I am sorry your daughters are still with your ex and hope you have contact with them.
Are you seeing a therapist (counciller or psychologist) - they can give you strategies to get through this - it takes time but things can get better - take care and keep posting here is you need support or answeres to questions MBC
