Hello.
I am sure there is always a way out. Since i do not know the details, my reply will not be specific. It seems you can benefit from a therapist's consultation. You have a strong motivation for fixing the problem (siblings). Use that motivation to work towards exploring your deepest thoughts and beliefs about the situation you are facing. Set specific life goals for the next few months. These goals will help you stay focussed. And every action and thought of yours can be weighed against the goals, and corrected if needed.
A therapist can help you in this process. Take care.
