Hey everyone, I'm new to this subreddit so forgive me if this is a basic question. 

So I've recently reentered into a relationship with an ex girlfriend. We love each other dearly but I often get into my head about annoying her or frustrating her in some way. I've dealt with my anxiety for a while and know that it's really all in my head - I know that my personality doesn't annoy her, she loves me after all - but I still get anxious anyways. 

For example, I currently have a friend in town so I haven't seen her as much as usual. She asked to hang out but I couldn't do what she wanted because of time constraints, and I got worried she would be mad that I said no. We decided to quickly see each other for coffee, but I was anxious that she was upset we couldn't do what she wanted. Of course she wasn't, but she instead got frustrated I was anxious, that I didn't talk much, and that we didn't get to spend quality time together. 

I know that she loves me and wants to hang out, but I get anxious anyways. I could tell she was frustrated because I was anxious, which just made me more anxious. If I wasn't anxious in the first place, we would have that short but good quality time together. How can I help get out of my own head and "just be comfortable"?

Thanks in advance!
