Lost. 1week post Eptopic surgery

i dont know what to do. after trying to conceive for 15months, miscarriage in January, i finally got a BFP early june. we were sooooo happy. after 3 days of testing last week and no results we found my baby above my right ovary and surgically removed 2 hours later. i am very lucky as i experienced a intra-abdominal pregnancy, my baby wasnt in my uterus, tubes or ovaries i still have everything. it had nestled into my cavity and created its own arteris sourcing blood off my right tube. i cant shake the loss. i feel so sorry for mu husband as he doesnt know how to console me, frankly i dont even know to be honest. to make matters worse is my best friend is pregnant and would have been 3days behind me. i feel so awful but i cant even talk to her because i cant shake the fact that she has what i had and want soooo bad. shes great and avoids the subject but little comments like 'im so tired' or 'im feeling a bit icky' just stab me in the heart and i just wanna bite her head off. am i crazy? how do i get over this? im usually the most positive happy person youll ever meet but i feel like i will never be happy again.
