How do I know if I’m masking?

I’m a woman in my 30s and haven’t yet been diagnosed, and only recently familiar with masking and what it is. The problem is, I feel I have been masking my entire life and now don’t know what I am masking and what is the real me. Any tips on how to work out what I am masking and what is the real me?

I score just over the threshold on the RAADS-R test and the AQ50. However score very high on a masking/camouflaging test. It also makes me wonder, am I actually autistic or am I looking for answers that aren’t there?
