Any advice on how to come to terms with the fact that I might be aro/ace?

I F22 have never had a romantic relationship even though I always thought I really want one. I don’t think I’ve had that many crushes on people and don’t feel like I what attraction really feels like. Because of this I’m starting to wonder if I might be aro/ace

My biggest issue concerning this is that I feel really sad at the thought of never having a romantic partner and never getting to experience romantic love. I’m also scared that people are going to start seeing it as a red flag that I haven’t had any prior romantic relationships at this age

I have a hard time not feeling like I’ll miss out on a beautiful part of life and that I’m “doomed to be alone” if I am indeed aro/ace. I have friends and family that I love but that’s not the same as having someone to live with and share your life with

Sorry for the vent, I just wanted some advice on how to determine if I might be aro/ace and what has helped some of you on your acceptance journey
