Is it normal to feel more anxious when you're alone?

This is quite common with anxiety. When you are alone, you don't have many distractions that cause you to take your mind off of things, and so it just starts racing with possibilities and scenarios. If you feel anxious when alone, talk to loved ones or play with pets. If that isn't available at the moment, you can also practice your hobbies/talents and listen to music to take your mind off things.

Yes. Being left alone with our thoughts can often be the times when we are most anxious, as it allows us the time to reflect on some of our more unpleasant experiences and/or ponder our worries of the future. Personally, I find spending quality time with a good friend can help alleviate this state of feeling, but it is something I still fall prey to, especially after following an experience in which I feel I may have done something incredibly embarrassing.

We might want to be careful on how we use the word "normal", because normal is defined as "conforming to a standard; usual, typical, or expected", and by answering this question with the meaning of normal in mind... I would say that it is not "normal", however, it can be common. Many people have separation anxiety or feel unsafe or insecure when alone.

Of course it's normal. Being alone makes people feel stressed out, and that there is nobody there to help them should something happen.

Yes, I believe most people experience some anxious feeling when alone. Maybe not every time when they are alone, but at least once everyone experiences anxiety when alone.

Yes of course it is! When alone it is generally quiet and no body to speak with, anxiety tends to play on a quiet mind.

Yes, my mind likes to analyze everything, and when I'm by myself, I dwell and spiral fast. But even sitting on the couch with my pets can make me feel not so alone , having a tangible entity near helps me and can distract me from those spirals.

When you're alone I always find your mind overthinks as a way to occupy itself. Everyone has different minds and different bodies, so it definitely isn't abnormal. We all feel anxious at completely different times - we just need to learn about coping mechanisms to make ourselves feel better when we're having some difficulties :) Talk to a listener if you're feeling anxious or alone, and remember to smile!!

Yes in fact so many people feel anxious when there on their own it's more and more common breathing Excerises help alot

I think that sounds pretty normal. Some of us have social anxiety and are more nervous around others, but it's totally reasonable to feel anxious when you're alone.
