Starting hormones is very gender affirming, and usually comes with a level of euphoria. This can last for a while, but generally evens out in coming weeks or months. For many people who haven't quite convinced themselves that transition is the right thing, this euphoria can make them decide it is, and the sooner the better. Recognise that you are euphoric, and your body is getting used to a new hormone balance, and avoid making important commitments for a while.
But, congratulations on starting your hormone journey, and enjoy the feelings!
