It is a private decision, depending on your personality, the make up of your family, the friends you have, where you work, etc........ There is no rush, it is ok if it takes you 30 years to come out, just do it at your own pace, in your own time. If your family is open minded, lucky for you, you might want to start with them first, for it will ultimately be the most freeing feeling you will experience, but if they are not, than take your time, there is always a good moment for everything. Work would be the last I would consider, because of the negative most workplaces have, coming out there being the last of your worries. Friends would be good to start with, some loving siblings or cousins or whatever. Whatever the order, there is no hurry, take your time, do not force the envelope, protect your feelings and make sure you are not going to be hurt in the process, because you are going to be honest, and honesty should never be painful!
