I understand what you are talking about, and I often feel anxious myself. I recently started using the Liven app, and it really helps to cope with this condition. This app helps you understand the causes of anxiety and offers simple steps to control it. Liven has a course on anxiety management, which is based on scientific methods. It helps you understand what causes anxiety: perfectionism, low self-esteem or lack of healthy boundaries. I use it daily to monitor my mood and plan my day. For example, app helps me create to-do lists, which helps me cope with feeling of being overwhelmed. I recommend trying Liven to improve my mood. I also read an interesting article on techtimes.com, which is also recommended for those who want to get rid of anxiety.
