5 weeks and 2 days and freaking out

Jessica
This is my second pregnancy my daughter is 6 years old and I do not remember what it's like to be pregnant. I been cramping lightly daily and breast tender along with sleepiness and mods swings. Today I woke up refreshed with no breast pain but still slight cramping and the feeling of fullness . I'm terrified of losing the baby I don't know why I'm so scared and can't stop looking things up and ruminating on this. My breast feeling normal set me in a tail wind and I started to cry thinking my symptoms were stopping. I'm also moody as heck and everything is annoying me. Am I going crazy
