Career and Relationship: i was born 5th may 1982, now i'm a single mother with 10y/o daughter.

working in construction field as site supervisor. but i'm thinking to get promotion but i can't decide which field i should go. should i continue my electrical engineering study, or i go for safety officer study? I'm struggling to get financially free life just to go see my invisible boyfriend in Canada. He also born in 1982 Sept 24. We never met each other in person, but we are in this invisible relationship since 2014. its started from game conversation, facebook, whatsApp, and so on. is it worth it for me to continue this relationship or i just have to switch my brain to reset everything and go for real person?
