Help needed

I'm feeling extremely anxious right now. First time since 2003. For reasons too long to get into here, I've had to cut my meds in half until the middle of November. The reason for this is that my pharmacy will not renew my prescription until October 28th because they say it is a controlled substance. Normally this would be fine, because I have enough to last until November 2nd, but I'm flying to Ireland on October 19th. This means someone will have to pick up my meds for me and mail them to me and Ireland! And it will probably take at least a couple of weeks to reach me. So the only solution my doctor and I could come up with was that I cut my medication in half until the prescription reaches me and Ireland.

I don't want to give into these horrible anxious panicking feelings like I did for most of my life. I'm having thoughts of canceling my trip but of course I don't want to do that because that's what I used to do in the past, and also I haven't seen my granddaughters in 3 years.

Any words of encouragement or hope you can give me would be greatly appreciated. This is my first time posting.
