Worried about bestie (ASD related)

[RosesinGranGransgarden]

My best friend is isolating herself more and more. She lives with parents so I know she's ok but she has stopped replying to all messages.
At the start of lockdown I set up a group chat with our group of friends and we would all watch films together and chat on WhatsApp about them. The last two times she hasn't joined in. I've sent a few different messages directly, asking if she wants to meet up or watch something together. No response.
She has obsessions which she often posts about on SM. I've noticed these posts seem to 'ramp' up when she's feeling down. The other night she was posting content every twenty minutes but not replying to my messages.
I'm torn between 'maybe she wants to be left alone to concentrate on her passions' and 'no, this isn't good, she needs to leave the house and talk to someone.' I've suggested we meet at a local park and I'll bring a take away, but maybe I should just show up at her house and bring her the food so she knows I care. I know in the past she has said that she is glad that she socialised but dreads it before, I guess the problem is that she's had months of not having to do it, and now she's built it up as a big worrying event.
Guidance please.

YANBU just friendly OP.
I would get something she likes and send a text before leaving then just show up. ☺️
That would work with my friends, but you know her better than anyone here.

That sounds very thoughtful of you.

She could have got so used to being at home that she now fears going out.
I dont think you'll be able to tempt her to meet you.
I think the best thing to do would be as PP said, just text when you are on the way over to her house. Dont give her prior notice as this would give her time to worry about it.
