What is making me sad

Figured I needed to identify exactly what is making me sad.
 
i miss the good ole days when we were a happy family.
The looks on my boys faces makes me sad cause they are mourning too.
i miss the way she used to hold me
i miss coming home to a whole family
i miss the thought that Someone loved me.
Im sad for my sons who are going to live the broken home life like I did
im sad cause future me is gonna be lonely
i miss planning for family vacations
im sad cause we aren't going to grow old together
im sad cause I feel like a failure
im sad cause I've been replaced
im sad cause our family took second place to another man
i need to make a thankful list but not today
