Can not properly eating cause anxiety or raise level of anxiety? due to my schedule i don't eat on time or sometimes eat once a day and i feel anxiety

Sure can!: Not living properly over time can mess up many things. A brief lapse of good practices in a young, strong person is fine - but nothing works well if poorly maintained for long. Don't accept excuses from yourself. Do manage a minimum of nutritious food as if it was prescribed. It is! It need not take much time and will save time in the end. It's important! Take care.
