You know I think it is possible to learn to live a good enough life. I grew up with tons of abuse from lots of different people and no nurturing figures too. That kind of trauma interferes hugely with normal human development. But I still think its possible to learn to live a "good enough" life. You can learn to manage trauma symptoms so they don't hijack you all the time. you can learn to be kind and nurturing to yourself and to expect that same treatment from others. I haven't learned to trust anyone yet but that still might happen.
Those "little" needs can be explored and dealt with in therapy so that relationships with others can be healthier. Do you have a good trauma therapist? One who understands developmental trauma will be able to help you the most.
