You replied to my post and now it's my turn to reply to yours! Haha.
Anyway- I absolutely think journaling or writing things down helps. When my anxiety is pretty bad, it helps me to write down what is bothering me and rationalize it. I kind of write a chart with the thought, what scares me about it or details about it, and then I go through and correct it with rational, positive ideas. For example, I have a big fear that when my fiancÚ and I get married and have a house, that I will not feel comfortable and will be so homesick and want to move back in with my family (we're pretty close). So I write that down, write about what that would be like and how I would feel if that happened, etc. Then the best part: I start a new page or new paragraph and write about what it will actually be like! So for this example, I'd write that I'll love my future house and I'll be very excited to decorate it to my taste, make meals with my FH, hangout and play games there with all of our friends, and have sleepovers with my best friend (fiancÚ!) most nights that he doesn't work.
I hope this helps. In general, I think writing out our issues gives them a lot less power over us!
