When i need courage to keep going I tell myself "you don't need anyone, you were not born attached to anybody, just to a placenta and you got rid of it already"

Do you really want to continue alone?

Now, friends and family are handy. Take into account that family are not necessarily those with the same blood. If your family and friends are unreliable then look for new ones.

I say that if you're old enough then emancipate and keep your distance from them.
