Moving out

So I have very bad anxiety an have been having panic attacks a lot more. A couple months ago me an my boyfriend were looking at houses an I freaked out an we agreed to wait. He found a house for rent that I kinda wanna look into but anxiety instantly kicks in. It’s not that I don’t wanna move out I just don’t do well with change and I know eventually he will get tired of me having excuses but I haven’t mastered my anxiety yet an it scares me that I might not ever feel ready. I just have good an bad days an of course the bad has a more affect on my decision.
