I'm sure you've heard this a million times, but if your friends abandon you, then they were not your friends. Nobody should make you feel bad about something you cannot control.

Depression is horrible, but it is part of who you are, like it or not. It doesn't make you a burden, or a bad person, it makes you a person with depression.

You need to worry about yourself, and not be concerned how much of a burden you are on others--let them decide what a burden is. The ones that matter will stick by you, and love you for who you are. You are better off without the ones who run away; they aren't worthy of your friendship.

And you have friends here too.
