LHS 123, welcome to the forum. I am so glad you posted and were able to express your thoughts.
As you can see you're definitely not alone. A lot of us went through something similar.
I can't tell you how glad I am that you love your son and won't shun your daughter if the WTS required it. That unconditional love is what being a parent is all about imho.
I won't sit here and tell you that the road ahead will be easy but it is manageable and although you may feel alone we are here to listen to you. Even if sometimes we don't have the answer please feel free to vent your feelings.
I have kids and also would never shun them no matter what.
Good luck LHS 123 and feel free to PM me anytime.
