Anxiety over being anxious?!

Ok guys, so, I was thinking about a very good thing that may happen in the future.
A road trip with lots of friends.
But then, I felt something that I can't even explain... a anxious-bad-feeling about that good thing....
Something like:

- "Am I healthy enough with my anxiety problems to enjoy this future event?? No! I'm not ready yet!..... All the improvement I thought I had, is gone now. Anxiety is back. I'm lost. Its an eternal disorder. I will never be healthy again!"

Now I'm anxious about my own anxiety... After 3 months of peace inside. Omg
And even though I know this is Just Anxiety, because as I said, I've been an Anxiety Sufferer for years, and I know how annoying and bad it can be, I'm still scared and frustrated now for having this Revival.
This kind of thing can really happens? Does anyone relates with my situation? I really need some light from someone.. some relief... some kind words... Please dont feel pressure to lie to me just to comfort me and make me fee better. Thank y'all friends
sorry about my english tho

Don't worry, you are not alone! If my anxiety doesn't completely stop me from going out then I just spend time with my friends trying to act normal because I don't want them to see my anxiety. They all know about it, but if people sense it then they are more likely to be effected by it. So I stress about myself stressing and that making other people stress and then ruining everyone's night. It's a cycle I am also trying to break..
