This is not uncommon. Coming out is a difficult, scary thing to do. It took me six months, from the time I decided I had to do it until I actually did.
What helped me was to have someone check up on me from time to time. I had a member here who checked in with me from time to time to ask, "Have you done it yet?" It was kind of like nagging, but I knew it was meant kindly, and it did, in the end, help me to actually take that step. It is easier to keep a committment if someone will hold you to it.
