I've had a few. Some pretty terrible parts of my childhood, I won't go into details.
Living in a city I didn't know, with no friends or family nearby and I job I was way out of my depth in at 20. My parents had moved 250 miles away just prior to my own move and it was going home to stay at my dear grandads every weekend that got me through. I had my own flat but being with him made me feel like someone cared and I had a place in the world at the point.
When my beautiful DD1 was stillborn 5.5 years ago. I delivered her at home in the middle of the night while my exH slept. I was in so much pain and so scared and so heartbroken. My dear grandad died of cancer a year later, after being very ill for 6 months. There was then a terrible array of family fall outs regarding his will, which left me feeling gutted and very betrayed by the majority of my wider family. I still can't think about this time without crying, but I am very lucky to have a beautiful DD2 now who is 4.
The first half of 2019 was horrendous. My best friend killed herself and I felt (still feel) a huge amount of guilt at not being able to help her more and stop her. In the aftermath of this I realised my very unhappy marriage was actually a rather abusive one, and that I was basically replaying my own childhood. This was a crashing realisation and ending the marriage was very hard. My exH is and always will be a difficult person to be involved in and I feel huge guilt about the potential impact of it all my dd.
However, there have been many good things too. I'm now qualified and work in a job I love and find very fulfilling. I am in a great healthy relationship with a man that is the love of my life and I have my wonderful dd. Tough times happen to us all, that's the way life goes, but it goes the other way too. Things will improve, better days will come, they always do.
