I don't know exactly how you handle things so I can't really say what is best, but I do know once I started hormones, I was much more emotionally stable. It doesn't work that way for everyone though, some people seem to need an adjustment period once starting HRT to get used to how emotional processing differs on new hormones. So the way I see it, starting now could help or could hinder you, all things being equal I would probably go for it in your shoes based one what little I know. If it is too much to handle you could always stop.
