Pull me up

When I say something about wanting to grow up or to be a better person, two of my family members that I won't mention here mock me and say that it will never happen and that I'll never reach my goal. I know they are just joking, but it hurts my feelings. Nobody cares about how I feel. 

They call me a crybaby and tell me I am too sensitive. Nobody is trying to console me. Nodody wants to apologise. I hate it. I hate it so much.

 My parents always told me to step up and show initiative. I am not against it, but they are just telling me to do it without supporting me. 

They are always there to violate my privacy but not to be there for me. " Because we care for you " , they say. Can't they just accept they are not doing it right ? I am not my sister. I need a lot of space. I want to live in my own little bubble and the least they can do is be there for me, not suffocate me with their intrusive behaviour.
