Admitted to others for the first time last night that I was questioning being ace. Feeling very lost and lonely.

So I (21F) have never been in a relationship before. For the longest time I’ve considered myself a lesbian (and that still may be true) because I’ve never had any desire to be in a romantic relationship with a man, but often fantasize about romantic relationships with women. I’ve had crushes before, but VERY rarely, and those crushes never include sexual attraction.
Last night I got drunk and blurted out to my roommates (who are all queer) that I think I’m asexual. This was after they asked about my dating history, and I couldn’t stand the way they looked at me when I told them I’ve never been in a relationship before.
I haven’t been able to stop thinking about it since. If it is true that I’m asexual, then that would make a lot of sense, but there’s a part of me that can’t fully make peace with that. I’m not repulsed by the idea of sex. In fact I do find myself wanting it from time to time. I’m also embarrassed to tell other people about it because of the perception that asexuality is childish and immature.
Anyways everyone says that being honest with yourself will help me feel better in the long run but I just feel so much worse than before. I don’t know anyone else irl who’s asexual so it feels a little bit like I’m the weirdo. I wish I could feel happy about this but I really don’t and I don’t know how to feel better.
