It's a downer when others do not validate your experiences and feelings. IrisBloom is right about therapy and this forum being the place for your feelings and thoughts to be acknowledged and validated.

Often times, it's difficult for others to believe how rough our situation was. Most people tend to say along the lines, "They're your parents after all - they must love you." Sometimes what we really need at the moment is for someone to just sit and listen. So share or vent away if you want to.
