Just looking for a lil help

These past few years have been just the worst for me every since I lost my dad it's like my life can't be right I haven't had time to be who I use to be sometimes I feel like running away from it all but I can't leave my kids alone and lost but its days I wake up and feel so sad and depressed that I don't know what to do with myself let alone be a mother nobody ever cares how I feel around me I feel so lost like the world is still moving and I'm at a stop every day I'm just on the verge of crying and breaking down I don't have the support I need from family or friends and my kids don't need to know mommy's not doing great I'm just so so lost
