I've criticized my best friend for crying to me that she couldn't handle her kids and wanted them to go live with their dad. I have started to feel that way too about my own child and I am so ashamed

I used to give my best friend grief because she'd call me crying about how she can't handle her kids and wanted them to go live with their bio dad. Before I was a parent, I was disgusted with her when she'd tell me that. I'd think "What kind of mother is she, to want to just let her kids go like that". But I have begun to feel something similar.My husband and I are still together and the relationship is good. But he works 12 hour shifts so I am alone with our 2 year old pretty much all the time.Taking her in public is a nightmare. Screaming, tantrums, every single time and I'm always alone so I have to do it by myself and I just flat out don't know how to handle the public tantrums. It's getting so bad that I thought recently that I could understand why my best friend said that. I'm getting to where my child is breaking me down so bad mentally that I just kind of wish she could stay with her grandparents for a year until she grows out of this.I hate myself for even thinking that. I don't know what to do. I'm married but pretty much a single parent since my childs father is either working or sleeping. Is it normal to feel this, will it go away? via /r/Parenting http://ift.tt/2938EqE
