Taking it one day at a time

Well yesterday I got a call back from a cousler and I wasnt home..so I called her back so waiting to set up an appt.I need something to change...I just feel so sad and dead inside..nothing seems to make me happy anymore..I have the greatest 2 kids anyone can ask for...and all i want to do is lay on the couch and cry........
3yrs ago i lost the greatest man in my life..My daddy..he had a stroke and 2yrs last lung cancer took him away from me..we were like bestest friend.he was the one man in my life t hat never let me down..i could turn to..talk about anything....we had uniuqe relationship....i wasnt over close with my mom..but after losing my daddy.she started dating this guy...and has chosen him over family.she lives 10mintues away and has only seen us and the kids twice last year...its like she just doesnt care...just kills me inside..family was everything to my daddy...AND she acts like its nothing......why do i always get kicked in the stomach..from family to friends????? Are there real friends out there anymore
