i need help! i cannot do it all on my own and still be pleasant and bubbly.

I feel so trapped in my marriage. We have been together since high school and I just feel like he will never grow up. I'm mentally exhausted. But terrified to end my marriage because I have been a stay at home mom for 10 years and have no idea how I would support us.

i can't stop crying. i try so hard but am reminded over and over that i'm not enough and never will be.
