The love-hate relationship with work

Sometimes, I don't know and don't understand what exactly I should do with my work – should I stop working or should I quit relationships with everyone? And this is a very difficult question, because I can't live without either of them, honestly.

Work is addictive, or at least becomes addictive for some period of time every once in a while and then as soon as I start working on something with full focus, my relationship starts missing me. My girlfriend would be getting angry at me for not giving her enough time, and then if I start giving her time, I am unable to work with full focus at all.

I don't know how people keep the balance in their lives, because sometimes I really struggle to do that. Till now, I haven't lost my cool but it worries me how that it will be in the future, and how the situation will be become in the coming time.
