Hi!
I'm new to all of this too, I'm glad you felt able to open up and share these feelings, I guess sometimes being anonymous is a godsend. On a positive note, having recognised how you feel, your in a much better place to start addressing these issues. You're very clear on how you don't want to deal with things which gives you scope to explore other options and ways of dealing with these feelings.
I know you're feeling guilt because you appear to have everything you've ever wanted but maybe this is your body's way of telling you that all is not well. Are you getting enough time to yourself? Do you have hobbies and interests outside your family life? Would you consider online counselling as opposed to face to face? Perhaps if you felt brave enough you could even venture to the doctors and be very clear that you don't want medicine but more advice on coping mechanisms?
I hope that you're able to find a way through all this, you're not alone.
Much peace and happiness to you
Sooz
