The life of a Dad trying to keep myself and my life together after my daughter got adopted after I was in an in abusive relationship.

23rd August 2021. I lost my daughter to adoption a year and 10 days ago after being in an abusive relationship in which my ex told the social services it was me abusing her. I tried all I could to get my daughter out of care and failed. Everyday is a struggle as I blame myself. I am socially awkward and have anxiety talking to anyone including family and friends. I have become a shadow of myself and stay in my room when returning from work and always avoid conversation with people. I have broken up from my recent girlfriend over arguing as I'm still a mess especially since she is now pregnant and it has made my thoughts of regret, sadness and anger back. I want to love this baby as much as I did my daughter and I will not allow my feelings to get in the way of that but I will always feel sad and guilty that my other daughter isn't with me. I need help to try change my feelings. I have days where I have a good day and feel guilty as i only gave good days when i try not think about the past. I want to remember my child and think about her but not fall apart everytine I do. My ex girlfriend who was abusive and the child's mum is pregnant with another guys baby and she is getting tockeep the child which is killing me more as I was abused and lost my child due to her lying and saying it was me. I don't see a way I can get my life back on track but I have to for my unborn baby. I want to fix things with my unborn babys mum and have a happy life but everyday I'm hanging by a thread to not break down.
