Hello terableedepressed, I am sorry you are struggling so much right now. Depression is awful and can make us feel bad and guilty and it can make us feel like it is our fault. I have briefly looked at your profile and your family are old enough to understand. You can explain to them as best as you can and you can show them information either on the internet or give them a leaflet about it.

I can also see on your profile that you have been on medication for 2 years and you feel that it is not working, please go back to your doctor and try a different medication or it may need adjusting. Psychotherapy is also very useful so it would be good to look into this also.
