Reina,

Grieving the loss of a friend and a relationship along with not feeling supported or included will make me feel quite depressed.  I would give yourself some grace and time, painful as it may feel now.

You are not feeling any joy in the activities you are doing.  I think that is natural for that is what grief does to us.  I caution you to judge yourself as being weak and dull.  I also caution you to generalizing that “people never think of me or want to be around me.”  There will be others who do and they have not found you yet or you with them.

I suggest meditation, exercise and getting out in nature to make part of your life.  This will help nurture you.  Get online support such as here as well.

I remind myself whenever I am feeling lost or experiencing something crappy in my life, that everything is temporary and this too shall pass.
