Hey!
I see you're back from China and hope all is well.
From what I understand you don't feel fondly of your family over some issues, which is a shame. I hope that is right and I haven't remembered the wrong person.
From what it seems you don't have drive even though you said that, you are telling yourself you can do what you want to do. On top of that you are missing the China experience and clinging on to it.
You, like everyone else just want a purpose or an aim to work towards. The thing is no one going to give you it, you have to ask yourself and find out yourself what that is. From there you will know what to do.
The only wedge stopping you is yourself, you need to just push yourself out there. Do you think you're great at designing? Then look up career paths in that area, go for an interview, talk with people in that area, etc just to give you that feel of actually doing something. You may find it is a hard task to do but once you do it you'll be happy.
If you change the way you are feeling right now and then the feeling comes back that stops you don't let it beat you down.
Realistically rememeber we all want a job or career path we enjoy or love. People will tell you they have achieved that and others won't, what you need to focus on is what you want, even write it down and see how you can get there or at least fit the requirement enough to make you think it is worthwhile.
You just have to push yourself or you will never really know.
