do you typically worry about that sorta stuff? I ask because I have anxiety and I worry about stuff exactly like that all the freaking time.
Remember- it's alright for you to be worried, it's nothing to be ashamed of. Don't get yourself down because you're feeling nervous about something.
With that being said, there are lots of things to do to keep yourself chill! I meditate sometimes when it's getting bad. I always have something in my pocket to play with (a little plastic animal for example). If you feel like you're starting to panic, close your eyes. Focus on yourself for a minute. Focus on how you're feeling, and just let I happen. Take deep breaths, focus on your breath. Let it pass, because you're strong and it will ALWAYS pass my friend.
If you think that these feelings are recurring and are serious, please take time to talk to someone you trust about it, and maybe see if you can see a counselor who knows exactly what you're going through and knows just what to do to help you feel better and be better prepared next time you feel that way.
You're welcome to message me to talk more about it if you like, since I've been coping with anxiety all my life I know what it feels like and I'm here to help you through it!
