Whats with those Crazy Milestones?

Today has been an emotional roller coaster. One minute I was yelling, the next I was crying. Then happy and laughing and finally back to yelling and now crying. Today is Petey's fourth birthday. I look at my son, his fathers exact replica and I weep. So proud of my little man and so sad that his daddy is not here to physically see it! I remember four years ago today. I was so happy. I was also so nervous. I was raised with all women and what was I going to do with a boy. But once I held him in my arms I knew it didn't matter. I loved him. I think back to those first few moments and I remember the way Pete held Petey so close. He was so proud to have a son. His son. Why God? Just Why? And really does it matter. He is not here and I am. I know, I know, I am so blessed to have three beautiful children that have their Daddy's blood running through them. But still.
  My heart is heavy tonight. I am sad. I sat on the floor or Aryanna's room tonight as we sang prayers. and the one song that Pete always liked to sing popped into my head. I had stopped singing it b/c it was just to hard. But I thought, "tonight, I will sing it for Petey". I made it half way through and started to cry. I couldn't finish. I sat and held Chase Leo on my lap and rocked him. I felt like In those moments I was going through my own private hell. Made just for me. I needed Chase Leo's little body close to my heart. So I could feel his sweet baby skin next to mine. Aryanna, and Petey, had fallen asleep. So they couldn't hear my silent tears. I kept thinking how sad I was that Pete never got to hold Chase Leo. In his big strong arms. How today he didn't get to marvel at his big little Petey. I sit and I wonder, What am I doing?...
  I have been struggling with Petey. He needs his Daddy. Damnit he needs his Daddy!!!  I know part of Petey's behavior is being four, but at times I feel like I lack in so many ways. It's hard to be a Daddy to a little boy when you are just the Mommy. I need Pete to help me. I feel that maybe the reason Petey is so head strong is my fault. Things just fell apart after Pete passed. I mean Petey was only 2 and a half!  What does he remember of his Mommy... So many things that I let slide. Because I didn't have the energy to argue. I just didn't know how to do it any other way. and Now am I paying for it? Is it just Petey?  I don't know. I keep having these feelings that if Pete was here he would have all the answers? That he would do it better? But would he have the answers? Could he do it better?
  I don't know. Are these thoughts normal? rational? I know that I havent' slept well in too many nights. Chase Leo is getting tow teeth in, therefore not sleeping. So Mommy is not sleeping. Is it lack of sleep. On top of that Last Tuesday was our would have been anniversary. It would have been 8 years.   To many milestones all in a row. April 21st was 17 months since Pete has passed. April 26th our would have been anniversary. May 2, Petey's birthday. and finally May 9 Mothers Day.  Sometimes it's too much. How do I just keep going.
  I just keep thinking if I can just get through another night. Get up in the morning. And hopefully one of these morning Aryanna will be on time for school. I trudge on. What choice is there. another day, another time out, another load of laundry, endless bills to pay, and more worries upon worries. Plus the big one how much am I really messing up my kids. I don't feel that I give them enough of my undivided attention. I am always in four otheter places,  And still I wonder if Pete was here with me would he do it better?  Would Aryanna still be late for school? Would the bills still pile up? Would Petey still be so argumentative? Would Aryanna still be so anxious? would I? And what of Chase Leo, He at least would know his Daddy.  What of these thoughts.. lack of sleep? Missing Pete? or just too many milestones in a row? Maybe all of them. Or maybe yet another way of grieving. I don't know.
   I know that in this moment I am not supposed to have all the answers. But I want them. I want to know that I am not doing it wrong. That Pete wold not do it better. Is that selfish?  That in this moment I am doing the best that I can. However I feel that that best is just not enough.. With this day the way it went, was maybe not the "best" fourth birthday that he could have had. between Mommy's many crying spells. My hope is that he will remember his new bike, his train cake, and his new Thomas movie. But Petey being Petey, and as sensitive as he is. Nothing gets by him.... And yet again. I wonder "Would Pete do it better"/
   The answer is still the same.. "I don't know."  I guess that I just have to chalk it up to being yet another "Crazy Milestone" another moments or moments that I survived. That in this day there was laughter, there was silliness. To remember the kids and I were surrounded in people who love us, and care for us. Who may not always understand  why I am the way I am. Or why I think the way I do. I hope that in the years, and Birthdays to come. That my tears will be less. That if the tears do fall.. it will be accepted and loved and kissed away. That on Petey's next birthday I can look to the heavens and Thank Pete for the wonderful gift that he gave me. This life. However not perfect. But Crazy, just the way it is supposed to be.
