Hi thank you for the advice for my situation.
1st off I have had many of chats with my wife on this topic. She has said to me if I stay in this job in fear of upsetting my parents I will just have to accept it and the risks. Now don't get me wrong we are very close but she has a hard time understanding anxiety. She see if we lose our jobs we call the banks put a hold on the loans and get a new job. On the flip side we love working together and the traveling that comes with it.
2nd problem is with my parents.. They believe they are doing the best thing for me by building this business up for my future. I have a hard time talking about it to them as this is their lives work. I've had a few arguments with them about it and they also don't like me constantly asking for reassurance all the time. I understand that part but I can't stop it at the moment. I also worry if I leave they will throw in the towel to and lose everything.
3rd my psychologist has recommended that I try to build my confidence by finishing my year 12 study and work on new skills. Also she said to slowly work on my parents and not trying to rip it off like a bandaid. Start small as I'm an only child so they are very attached.
Now I really don't mind this job but I'm not sure I have the strength.
