Hey there, patience is a virtue and a complete nuisance!! You are doing all the right things.......starting the journey the healthiest way.
Waiting for a diagnosis is the hardest time.......you know what they say......"Acknowledging that you have a problem is the hardest step of all".
Take your husband with you to your second session if u both feel comfortable with that.......he will need to learn coping skills as well as you. It is a journey that would be good to take together.
Straying off the path is not uncommon.....we are all human. Its getting back on the path that is the true test and the most satisfying.
Your kids will be fine. I have been mentally ill all my sons life and he is 14 now and he is a lovely, caring, cheeky boy. It is not bliss all the time and we still have the normal family disagreements, but he is well adjusted, does well at school, has good friends, and has a good social conscience.
Good luck and keep us posted.........keep breathing deeply and peacefully......be still when you can and an answer will come.
