<human>: As the title says, I think I have anxiety issues, but don't know what to do about it. I know people will suggest seeing a therapist, and I think that's a good step. I am moving to a new country soon though so won't be able to for a while.

I constantly overthink and ruminate everything. The most minute things like texting my friends, afterwards I'll sit and reread the texts and wonder if I should have phrased things differently. Or why they haven't answered as soon as they have other times.

I also feel very uncomfortable (I don't know how else to describe it), when I predict or expect things to go a certain way (e.g interactions at  a party or with friends) and they don't go how I expect them to.

I can't really pinpoint the feeling; I think it's anxiety. But it just feels overall uncomfortable and like I've somehow fucked something up.

I also think back of things I've said when out with friends, and feel upset over some things I've said if I regret them later.  Usually it's really minor insignificant things, but I for some reason obsess over it.  

More often it's with people who are new, or who I want to like me, or I have some interest in. But often with just platonic friends as well.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I ruminate over things that cannot be changed and are unimportant, and feel anxiety when things don't go how I predict. Ways to cope or try to modify my mindset and thinking?
