Really struggling

Hi everyone, I’m just wondering if anyone can advise where to get support. I have tried to reach out to my health visitor and was just told to contact chat health, so I did that and was told to contact my health visitor. My little boy is having so many tantrums and just crying all the time, it’s really getting to me and I’m struggling. I’ve been having relationship problems and it’s all getting on top of me. I’ve ended up really shouting at my son today and have been crying most of the day. I do not want to be a parent that shouts, but I’m really struggling to regulate my emotions and I need support 😭
