That thing that shimmerz said thinking of another young person with the challenges you have experienced to bring into perspective your worth - you can also dig out an old photo of yourself as a very young child. See what seeing them (I don’t know what your pronoun is) evokes in you. I bet you will feel a powerful sense of love, protectiveness, compassion for an innocent, vulnerable, precious treasure. Know that is you. People do exercises remothering themselves when their carers have failed them.
Further to what shimmerz said about society’s misconceptions, there is an orthodox way of seeing things in society that is deterministic, mechanistic, linear. If you subscribe to this, you could get stuck on your physical conception and believe you are doomed. Remember this view is not an “objective truth“ though. It’s just one paradigm of a number on how the world works. There’s no need to be myopically, drone like, unawarely locked into the current orthodoxy. At least recognise that it is a choice if you do choose it after checking out other options.
I think there is a reason we are here. You seem to be an empathetic and sensitive person from what you say about abhorring injustice when you see it. Maybe a great understanding and compassion is what you gain and can contribute around.
Re therapy -if you’re new to therapy know there are many different schools.
CBT is one of them and it may suit you but if it doesn’t just look for something else. Different modalities may suit you better or a different therapist may suit you better.
