I'm so happy that I've found this! I have (almost) the exact same problem! I've finally found someone who is just a really kind and solid guy, but I've had crippling anxiety--the same feeling of dread that the OP has. I've had it in the past with other guys, but it was never as bad as it was with this guy. It's gotten worse, though--whenever I think of him or even get a text from him, I have this awful anxiety. When I spend time with him and talk to him on the phone, the anxiety is almost never present. I think I've now just conditioned myself to basically associate my boyfriend with anxiety.

To make matters worse, we've entered a long-distance relationship and it's been so difficult with this anxiety. I can't pin-point why I'm feeling this way, but I am happy to know that I'm not the only one in the world with this issue. So if anything, there's solace in the fact that it's not just me.

OP, I've actually talked with my psychiatrist about this issue, but this was when the issue was still relatively new. I'd like to talk with her again, even if it must be via Skype (I live in Japan now, though I'm from America). But I will share what she told me when I first brought up this issue--she said that you have to remember that relationships aren't perfect and there's so much gray area. She said to take it 1 day at a time and to not think ahead relationship-wise. She said that it's okay to be anxious and it will probably lessen as time goes on. You won't have all of the answers, and that's okay.

Though her advice helps sometimes, I'm worried because I think that there is something seriously wrong if I'm even having this anxiety in the first place.

Whatever happens, I hope for the best for both of us!
