Hey there! I know how isolation from depression can be. It creates a void within you that you can't fill. As hard as this may sound, maybe joining a support group might help you. You will be surrounded by people who feel the same way and it will give you a chance to connect with others. You can search for groups in your area. If your friends don't contact you anymore, then that's their loss because they're missing out on being with a great person. The pain can be intense when friendships dissolve but once you make an effort to connect with others again and make new friends, the pain becomes less and less. I am wishing you the best!
