well think about this the pain u feel from loosing ur mom is the same pain ur kids will feel knowing ur gone i watch two little boys grow up after finding there mom when they got home from school she used a rifle an they walked in on her dead she is gonna miss everything from graduation to weddings to grandkids to even college an their first home or first girlfriend i have attempted suicide myself after i was raped i lost my mom an husband 3 months apart had two miscarriages was widowed at 21 before my birthday had to take my dad off life support an the only thing that gets me thru this is my boyfriend he is the best an if i had a son or daughter that is what i would live for its been 4 years since my mom passed going on 5 an i still remember like it was yesterday an someday all i want is her an when i got pregnant it changed my life after loosing the baby i lost myself for a bit i know ur going thru hell but just remember dont make ur kids feel that empty spot that u feel or cry because they dont have a mommy anymore i watch two kids go thru this an on top of it myself its not worth it maybe get a tattoo on ur wrist that say this "I am worth it ;"

Sorry for your loss.
Stay strong and keep focus for your kids
