I had a great many sex and love cases where people were absolutely devastated when somebody with whom they were compulsively in love didn't love them back. They were killing themselves with anxiety and depression.
In fact most of what we call anxiety is overconcern about what someone thinks of you.
Convince yourself that worrying about many situations will make them worse rather than improve them.
Whenever you avoid alarming situations, you almost always increase your anxiety about them.
Worry itself is one of the most painful conditions.
