Hi @NOVA2023
I'm sorry to hear that you've had a suicide attempt and your childhood was not happy...
but this is a big step towards recovery from that and that's really really good...
The fact you don't remember much about your childhood is a symptom of having experienced Adverse Childhood Experiences (such as abuse of some kind, neglect etc) - often referred to as ACEs
Your core belief is formed before you're even in school and is based on how others around you treat you and react to you...
You feeling the way you do is NOT your fault.
Have you considered trying therapy? I'd recommend a therapist who specialises in ACEs and childhood trauma as well as being a licensed DDP (dyadic developmental psychotherapy) practitioner-
If you like reading or listening to books try reading The Body Keeps the Score or The Deepest Well. These are great books for explaining why your first experiences are so important and the impact.
Also try doing some affirmations- these really do help! Stand in a power pose in front of the mirror and speak positive statements over yourself... you might feel silly but just start in private, a couple of times a day, and see how you go.
Please do continue down this journey. It's going to get challenging but with a good therapist to support you the benefits will be huge and, without any exaggeration, life changing.
Be gentle with yourself but allow yourself fo feel worthy of the effort.
