How do I explain the trans experience?

Hey everyone. I (21 transfem, somewhere on the feminine side of non-binary) have been having trouble explaining my experience with dysphoria (social and physical) and being trans to my parents, as they're the first people I've come out to who aren't already supportive. They don't seem to understand the concept of gender identity, why I feel this way, or what I want to do with my body and social presentation.

​

I've talked about wanting to change my presentation but not knowing yet exactly how I want to present, since I have basically no experience presenting feminine. It also doesn't help that I feel anxious whenever I talk with them about it. Any suggestions? How would you explain your experience? I know different people will have different perspectives, but hearing others describe their experiences may help me figure out how to word my own. Thanks in advance!
