Wavy, the big part of how I get past the self-sabotage is recognizing or naming exactly what it is that I am afraid of -- I think you've done that, so good job!
After I do that, I must accept that whatever I fear might actually come to pass. The worst possible thing might actually happen. That is the hardest part and it doesn't always happen on a timeline. It's hard work in and of itself, this acceptance thing, and it's scary, but acceptance always brings peace and clarity in its immediate aftermath.
The good news is, you've done this kind of thing before. You just did it! You have proven yourself capable! So girl, you got this. I know you do.
