Major depression?

🌞

Is a breakup a legit reason to feel major depression? Or I am I just weak minded? I am pregnant n have been completely abandoned n he is now taking me to court for custody of our daughter. I live for my little girl...she is my everything n he knows I am her everything. But right now I can’t take care of myself or anything. I lost my job because I just couldn’t deal, my house is trashed, I rarely take showers. I should hate him but I love him more than anything. Except my babies of course...everyone is telling me I should hate him but I don’t. I’m crushed, lost, feeling really hopeless. Why can’t I get it together n move on?! People go through these things all the time. I have always been depressed but have hid it well. But I just don’t care anymore and everything in my life is being affected. I’m scared I will never get past this. I’m scared I won’t bond with this baby. I’m scared I’m gonna lose my little girl. I’m scared he’s never gonna hold me again or text me funny videos we can laugh over together or kiss me the way he would. I’m scared. I miss and I love him. But I feel stupid that I’m not strong enough to handle this more gracefully and pick up my life and get it together. I am lost and don’t really have friends and just don’t know where to go from here.
