Things that used to make me feel better do not work anymore.

Hello and welcome to e health forum.

From the description it seems that you may have a anxiety disorder and or depression probably due to being lonely, which is probably resulting in a low mood.

You will need to de-stress and find ways to relax when ever you can. This you can do by various means, like listening to music, spending time with friends and family, learning a new art like music, reading books, being active in sports or at the gym, etc.

Other methods by which you can find relaxation and calm is by meditation and doing breathing exercises.

Regular physical exercise, good nutrition and stress management techniques will give you a basic foundation to build a new positive outlook. Have a positive attitude and develop a confidence in yourself that you have a important place in the world.

You may consult a psychiatrist or a counselor, who can take a complete history and with proper counselling and behavior therapy can help you start enjoying life. If needed prescription of medications can also be helpful.
