Hang in there.. know that it’s an obstacle to get through (the anxiety) but keep the thought in your head that you will be glad you overcame it and traveled in the end. Staying at home all the time waiting until death is no way to exit from life. That sounds horrid... if you are capable of being mobile on your feet still, take advantage of your good health while you still can.. you will be grateful that you did. Life is meant to be lived, not watched.. live while you can and soak up the beauty of traveling. Even if you’re lonely you can meet lots of interesting people who can make it worthwhile, plus seeing different scenery and a different culture... all of which enriches the self. Live while you can!!!
