Hi sleepless.
First off, well done you for the way you handled things last night in terms of CBT techniques, etc. That sounds like real progress!
As for the rest, let me say loudly and clearly that you are not being weak, weird, needy, inadequate or mad. You have severe, debilitating anxiety, which is driving your feelings and actions right now, and you're doing all sorts of things right to try and cope with it.
That bit where you hear a radio story or read something in the paper and whoosh, you're off to the races with terror and worry? Recurrent invasive thoughts, unfortunately part of the anxiety parcel. They suck. My DH tried (and failed) to ban me from all news sources for a couple of years as they left me so completely undone. You did well to reach out for a reality check to your closest RL allies and your MN support crew. If you can toss in some of your CBT as well today, you're doing great. Breathe. Take a 10 minute walk in the rain. Find something funny to read (there are some good options for the latter in MN classics!)
That exasperation or frustration you sense in your friends' responses is more likely their intense concern and desire to make all this pain and fear stop for you. But when you're struggling mentally, you feel ashamed and troublesome, so that colours how you read people's communications to you. But if you're concerned about bothering your RL friends, just keep coming here. Your friendships will survive this. YOU will survive this. Your baby will survive and thrive!
You are one day nearer to the finish line.
