Feeling empty

I am 20 years old, a mother & a hard worker. It has not been easy. My mother wanted nothing to do with me after I got pregnant at such a young age.. She was so mean, just plain cruel. My baby's father was just a loser. Luckily I had my best friend & her family who took me in. I've known them my whole life, yet it was a very difficult transition for me. I went through such a depression for a very long time. I finally realized I needed to stop feeling sorry for myself, not just for me but or my child. I met a guy back in April '11, it was love at first sight.... Kinda... We had our problems but still stayed strong. He's great with my child & amazing with me. Sounds good, right? The problem is sometimes I miss my family. I can be having a great morning but some how I just end up like outta my mind. I start crying, feeling like I should reach out to my mother... It's been almost four years since i moved out. I have two sisters who both got pregnant young but I'm the only one who made a mistake... I feel very sad right now because I just don't feel happy.. I can't talk to my best fiend or her mom because I feel like they get offended and might think I'm ungrateful... My now fiancé doesn't understand even though be tries hard too.. I recently found out my mom said my child and are a disgrace to her family and hopes I'm doing good but doesn't want to have anything to do with us for the time being... What should I do? How can I move past this?

you shouldn't feel like it was you because you will become bitter in life she may have something behind it and when she is ready to open up she will for now forgive her she may feel as if it is her fault
