Someone (22F) has feelings for ME (21F)???

(21F) I fear my emotions are too big for me to process on my own.
I am autistic and have ADHD for background context.
I don't normally schedule hangouts with friends because I'm not great with consistent communication and I'm agoraphobic in the way that I tend to avoid social interaction on default because I'm afraid of possible humiliation, awkwardness, and heartbreak. Though I do often seek out social interaction in some capacity because I think it can be healthy for me.
I started going to this 6-week LGBTQ+ social program in late June, but I couldn't attend the 6th week because I had a family trip to go to, but someone (22TF) wanted to hang out with me one-on-one before I left for my trip. It went great, though I felt there were some awkward silences, but I feel like it's just my brain overthinking things. She also wanted to hang out after I got back from my trip. I thought this was strange... nobody was ever really this eager to hang out with me more than once a month or at special events. I had a thought that this person liked me, but I kind of figured I was also overthinking this, because who in their right mind would want to be with someone who's awkward and not extremely attractive, right?
Well, we had lunch today before I had work and she told me she liked me. I told her I would have to think about it some more because, well, I do.

These are the thoughts I'm having:

1. It's not that I don't like her;

we’ve only known each other for 5-6 weeks, met IRL 6 times, and chatted online a little bit. I don’t know how to get to know someone with romantic context, if that makes sense. I’m tempted to just text her a rundown about various things about me lmao
2.

1. I am a complete virgin and basically have never experienced anything romantic or similar.

I’m wanting something non monogamous because though I’m very touch-and-affectionate-starved and want a romantic relationship, I also want opportunities to explore myself more sexually.
3. I’m really hard on myself and my mental health and confidence aren’t at their best, so I’m worried that those will get in the way.
Has anyone been in a similar situation? Does anyone have any helpful words of advice?

TLDR; friend I’ve only known for 5-6 weeks confessed to me and I’m trying to navigate complex feelings
