2cool, you can’t wish the dating process away. It is a process that everyone who gets married goes through. You are going to have to learn HOW to deal with it. YOU are going to have to learn what is causing your anxiety and how to handle it. For the irritable bowel episodes you can take Equilactin. You can get it over the counter. It balances the bowel between cramps and constipation or diarrhea. If your nauseous with the runs you can try pepto bismol and see if that works better. If that doesn’t help go see a Gastoenterologist.
For the anxiety you might have to see a therapist if you can’t figure out what is triggering it. Can you tell when it begins so you can do some breathing or meditation to stop it before it gets full blown? Is it only before the date, before he walks through the door or does it start when he walks through the door. Does it continue on the date? Does it get worse on the date or does it get better while the date is underway? Do you have anxiety during the phone call as well?
If you describe the episodes maybe we can give you some advice or suggestions how to handle it.
