I need sleep

Brittney • I love my husband and all four of our kids and our little baby thrush
IM 8 weeks and I can't sleep and when I do sleep I wake up in the middle of the night crying and maybe too scared to go back to sleep I keep having dreams that my husband is cheating on me.... and I know he never would do that has anyone else had dreams like this and what helped them sleep after waking up to them....
