Opinions ?

My son recently turned 1 in oct I have been doing everything myself since he was born my family helps a lot but his dad doesn't help at all I left him when my son was 2 weeks old because he was so abusive a few months later my sons dad was diagnosed with schizophrenia Hes had a really hard life his mom passed when he was 14 and his dad doesn't care much for him and I feel like that's why i've been so easy on him but he has never done anything to help me out hes gave me $50 at the most since my son was born and i had to ask for that he did start coming around to see my son but now he has disappeared off of the face of the earth again and im struggling by the time I pay for daycare rent and utilities im struggling to make it to my next paycheck i want to put him on child support but i feel like he wont pay and it will be a big headache for me plus I feel like i will feel guilty 🤦
