You are in good company.
For many, current times have bred loneliness and anxiety. Our communities have been wrapped in fear going on two years. This ongoing external and internal stress can cause us to lose our center and feel more and more disconnected from ourselves as well as from one another. Hence that feeling of loneliness.
In addition, many people I am seeing in my practice right now describe feeling seeped in anxiety. They will say "I don't know why I feel so anxious, but it's really becoming unbearable".
Free floating anxiety is a by-product of long standing fear and uncertainty about both their safety as well as concern about where the world is headed.
When we observe the division among family and friends. When we no longer have any idea when and if life will get back "to normal" (whatever that may be).
