Hey D$ML, as I see it, you are on the verge of trying to win back your H.
You are afraid to leap. You don't want to look foolish.
It is making you feel anxious--normal, very, very normal.
It's like the other stuff. There are steps. There is work. The more you do the work, the less scary it will be.
Don't be afraid of looking foolish--especially around here. You are a loving person. You loved. You have that ability and that emotion. It is admirable--not foolish. That is who YOU want to be. Always keep in the front of your mind--who do YOU want to be.
Don't worry about him, how he will look at this, nothing--it's all you. It's all the type of person that you are, that you want to be, that will make you proud of yourself in the end. And taking that leap WILL make you proud of yourself. You can proudly say "I did everything I could". There is a lot of power in that statement. I have been able to say it and I am proud as heck of the work I have done. I have been a fool for love--yeah me!! I admit it!! I will never be sorry that this is "me".
I hope that makes sense--you just need to dig in and the anxiety will go away. There will be goals and homework and all that stuff and you will meet them bit by bit and grow in your confidence.
