Can I have opinions?

I recently did some things on the weekend that I’m struggling to get past - I have quite bad anxiety at the moment which doesn’t help. I get very stressed and regretful and end up unable to do things or eat properly.

I am in a very casual and early stage thing with someone who I have already slept with & on one night of the weekend, we were intimate together (but no sex). The next evening I went to a party and met someone I got along with really well and was really lovely and went back together and we were also intimate (but no sex again).

I have a lot of worries regarding this but the most prominent today is that they were in such short succession. I am 22 and have not done something like this before and struggling with lots of feelings of shame and disgust. I have been meticulously scanning the internet for their thoughts and have been reassured partially in the sense that I am single and haven’t done anything wrong but I just can’t seem to get past this. I feel regretful and wish I’d thought more.

I am very much in my own head and I can see this impacting my life for a while if I don’t nip it in the bud now.

Any thoughts/ reassurance really appreciated. :)
