My boyfriend [23/m] does the slightest thing and it sets me [22/f] off.

What is the best way to calm myself in my relationship? By that I mean my boyfriend of 1 year and I will be hanging out in person, which is great, but the second we leave each other and he does the slightest thing that irritates me, it does way more than it should. If it was my friend I wouldn't care, but with him it could irritate me all day. It's so annoying and frustrating.

My mind races a million miles per minute at the slightest thing and I take everything personally. When he needs to change plans or forgets to call when he said he would, it sets me off. It's not fair to him, and it's draining to me. I just don't want to feel like this whenever we spend days apart. Ugh.

Has anyone else experienced this or have any advice? Any would be much appreciated. Thanks!!!
