No Yanel, you should never have to take somebody else's word over what feels right to you. Self-concept is a tricky thing, because ego uses it to limit what we know and accept of ourselves, but then there is self-concept and there is a deeper knowing.
Just trust the following things
You are complete in and of yourself, you do not need external validation to be all the things you believe you are.
You are being asked to wake up to who you are in a deeper more authentic way, so trust that this requires you to feel deeply lost at times and to question everything about life nearly from square one, in order to clear out your deep wounds that you would have never bothered with otherwise. You feel ashamed of aspects of yourself so this journey is asking you to accept yourself even more deeply and wholely than before. It will be a worth it ride if you can stick it out.
Astrology is a human practice, therefore it is not the cosmos, but the cosmos as interpreted through human beings themselves.
You are missing perspectives (edit: about your date of birth and your stars, as well as other sources of self-understanding) you will gain in the future; just trust that if you continue to need these answers they will one day unfold.
The universe operates on perspectives. Literally a same situation is lived entirely differently based on what the subject sees in it.

EDIT: besides, I feel like you've bought into the idea that there is 1 single astrology and that is your natal birthchart. It may very well be the main one, but if you're really in need of validation right now I invite you to consider things like your draconic chart, your conception chart, Vedic astrology that will bring out things in your Navamsa chart, and your aura (odd one out!! but equally fun
). Keep astrology ROMANTIC, keep it about SPIRITUAL UNDERSTANDING and fulfillment, don't just buy into principles because you feel pressured to or because you're currently unable to see things in your chart.
True story, when I look at my chart, or someone elses, before and after having healed a wound or a judgment (they are the same) the chart looks totally different to me and so many more truths, that I was blind to before, light up. So trust you're not seeing everything anyway. No one is after you judging your chart, it is just you.
