night time is so hard

Night time haas to be the hardest time of the day. The past few days i have been ok during the day have been able to function without falling apart. But night times are so hard i try to keep myself busy by watching movies or on the computer so i dont think bout losing my Macy. Im not getting any sleep i cant remember the last time i fell asleep  b4 5am its like when the sun comes up i know everything will be ok again. My doctor has given me sleeeping pills but they dont really help and just make me more tired in the morning. I feel as though i will never get a good nights sleep ever again. Bc of this problem i havent slept in the same bed as my fiance for about 2 weeks which affects the relationship i really need affection atm. I just dont know what to do any more
