Depression in pregnancy

I am 12 weeks and have suddenly got very emotional and down, i dont want to do anything apart from lie in bed and stare at the wall. I have had problems with depression in the past and have been to many counselling sessions which havent worked in the slightest so i dont want to speak to anyone about it, i cant take pills as it will harm the baby but i dont no what else to do 😔 i feel so apart from my partner whos giving me so much attention and love but i just cant bond with him like i used too 😔😔 what is the best thing to do i am so worried i will get post natal depression!
