Support please

So recently I became a single mom it’s very hard and I feel like I am completely failing at everything. I work at a job that gives me shit hours even though I’ve put in so much time. They say I’m almost there but I can’t help but to think they are lying. The hours make it hard for me to see my child let alone find a daycare that will except him that I can afford on my own. I just really don’t know what to do anymore I feel so alone and I know that I made the decision to leave his father. He was emotionally and physically abusive and I don’t want to be with him but I feel like I’m being pushed up against a wall and I just don’t know what to do anymore. I’m getting so depressed I’m so stressed and I just don’t think I’m gonna make it on my own. Any single moms have advice on how you did it? I just really need good vibes right now because I feel like such a failure.
