Idk if I’m screwed or

So it all started with meeting a 17 year old girl on a app called Wizz she was called Megan and we got talking and then we added each other on snap and it got very sexual bearing in mind I’m 18 and she was like sending tit pics and then she kept going on about how horny she was at first I was like apprehensive about it because I’m autistic I didn’t know what I should have done in this situation and then she started talking about how she wanted to see my penis and I was like uh why I was like kinda nervous about it and then after like her asking multiple times I sent a couple pics and a video and she responded with her sending pictures of her boobs and mastrubation videos and then out of the blue she blocked me idk why and I’m worrying that the fact is I had my location on she did as well but I really hope she’s not reported me i didn’t know what I was doing I’m a idiot I hope nothing bad happens im rly trying to get my life back I don’t want trouble with any of the authorities over this issue does anyone have any advice
