Ummm, then main question is why she didn't tag along with somebody right from the beginning. I can't imagine anybody saying that she isn't wanted, so why did she head off alone? So the developing insecurity throughout the whole year doesn't really matter. She was afraid right from the beginning, or something along those lines. What she is afraid of, we have not been told. Does she really believe that disbanding Fairy Tail means that everybody wants to forget their former guildmates?

And, furthering this, if she did develop insecurities during the past year because nobody contacted her, then she's being a tad selfish. She decided to head out alone. Looking at the chart, we know that Mirajane and Lisanna were together, Jet and Droy were close to each other, Thunder God Tribe is together. There's nothing to indicate that everybody went solo after the dissolution. Only thing that is certain is that Lucy went solo and then never tried contacting anybody. Thinking about it from a different point of view, we can say that the FT members thought that she wanted to move towards the future and didn't want to meet any of them because she didn't want to remember painful memories.

I don't think Lucy's selfish, which is why I think the reason given was pretty vague and mainly just an excuse to set the plot into a search journey.

@B214: But why didn't she travel with, say Wendy or Erza right from the beginning. If we have anything to go by her being the first person to use Unison Raid (alongside Juvia) and her speech during the Battle of Fairy Tail arc, she's a group person, going solo doesn't fit very well with her, although being a journalist fits her perfectly. Not disappointed or calling bull on the development, just saying that it's a bit weird and plot-convenient.
