Sometimes I feel like I can't breathe

I have so much stress, my boyfriend hit me I filled a police report no arrests wth! So I'm wondering what is going on! I am shaking from all the worry money what I should buy. I'm a first time mom, I'm looking for a job. I just can't sleep. I went to the "hood" today to get a affordable phone I just feel like this isn't the life I wanted. I am going crazy. I'm holding everything in. I just have a headache I don't know how to handle stress please someone help. How do I let go and start new. Any financial help is welcome, I just really am freaking out.
