I know how you feel. I'd become way too sensitive and excited when someone I liked was coming over to the point where I was paralyzed.

Something that has helped me is to stop focusing on them. If the house needs to be cleaned, then it should be cleaned because that is what needs to be done.

You should get out of bed because it is unhealthy for you and does not help. You have things to do, just like you had things to do before ever meeting this woman.

Meditate. Breathe. Slow yourself down. Go for a walk. Remain active without pushing yourself.

Do not hinge your emotions on her. She is not a rock, and to fix your feelings on her will make your moods fluctuate like crazy. You can still be in love with someone and thrive on your own terms. In fact, I'm sure that is something she'll appreciate.

Take it one step at a time. Invite her into your home. Make her feel hospitable. If you don't feel comfortable at your home, go for a walk. Take your time. You don't have to rush anything. Even sex. Even love. Take time to trust your feelings. You do not have to impress her. But you should strive to be authentic and open.
