Hi Mysocalledlife, and welcome to the forum. This is a great place to share experience and support.
Congratulation to your boyfriend on his sobriety! You're right to be proud of him proud. Is he working a program to help him maintain his sobriety as he moves forward?
Many of us here have found that that calm time, when our qualifiers aren't actively drinking, is a great time to work on ourselves. So much of our time and energy can be spent focusing on them, and their issues, that we tend to neglect our own needs, and personal development. As you said, even the ups and downs of sobriety can be tough.
Are you doing anything for yourself?
