It sounds like the issue is that getting labelled with a mental disorder is frowned upon in your society. I am basing this response on that assumption.

I have no idea what it is like in your country but if the help exists, take it! Don't worry about stigmas or anything else. What good does it do take make people think you are okay when you are suffering? You health and well-being are far more important than outside influences. Do medical privacy laws exist in your country?

Online help, including live chats can be very beneficial, but in my opinion aren't a proper substitute for professional help. This board and other places can certainly augment therapy.
