How far must I climb to conquer?

As I look back at my life, only a mear four years ago, I realize so much has changed. Not only things in life but myself as a person in whole has changed drastically. After a horrific break-up that sent me into a deep spiraling depression, a drinking binge, major weight loss, job losses, having my truck repossesed, an abusive relationship, a child outside of wedlock with a man who I thought loved me but was just playing on my emotions, being on the welfare system, not having a car/license, and not a place to call my own, you would think I would have been in the looney bin. (Im sparing a lot of details for this could be a novel LOL)I guess I was one of those people that had to make their own path in life and learn the hard way.
As we flash foreward four years, I think to myself, wow that was a serious mountain that I had to climb. But somedays I still think how far must I climb to finally conquer? Even though life is ten times better than it was back then, I still find myself battling things on a daily basis. I am now a mommy to a beautiful two year little boy by the name of Logan :) I find daily struggles with being a parent as we enter the terrible two stage. My patience is tryed on a daily basis. The word no must be said a thousand times in my house a day, if not more! In the midst of this, Im busy working very hard on my studies for College. I want more for my family so getting an education is a neccesity in the world that we live in today, not to mention the economy. So doing homework listening to a child throw a fit because mommy didnt "look" at him the right way can be a complete challenge. Now lets throw another loop in there. Im also engaged! Might I add to a wonderful man who I couldnt have ever imagined "wrangling in." He came into my life years ago but long story short, we ended up talking again shortly after my son was born and its all history from there :) He has become an amazing dad to my son and treats me wonderfully. He is supportive of me going to school and takes care of the bills and works really hard to put a roof over our head....but the downfall...its ONE MORE BATTLE LOL. As all relationships have their fights, we tend to butt heads a lot. He is as stubborn as I am but we do love each other.
Somedays I feel like Im constantly battling and climbing and fighting to over come the past that I made for myself. I know the past is the past but sometimes the choices that you make in the past are reflective on you as a person. I want people to see the bigger picture, who I am today. A mom, an almost wifey, a college student, an animal lover ( 2 dogs, a cat, a chinchilla, and a horse LOL) My family is my everything and I have made leaps and bounds to be what I am today. But somedays that past comes to haunt me and I feel I am starting the climb all over again....
