Ruined my life ..

I'm preganant alone and depressed .. My xboyfriend hasn't bothered to look for me or apologize for cheating .. I can't seem to get over him and my days & nights consist of tears and heart ache , how do I move on ? How can I make this pain go away ? ? I go to every doctors appointment alone , every wic appointment alone , every ultrasound appointment alone and it's just so hard bc I'm so hard on myself for giving my child life without a father ( just like me I had no father  ) .. ?
