SOS 😭😭😭

someone please for the love of god help me lol my son has always been the PERFECT child until he turned one 2 weeks ago. he is an absolute terror. he is constantly screaming and hitting and throwing himself on the ground. I can barely stand to be around him as bad as it makes me feel to say that. I didn't think this would start for a long time. tell me I'm not alone.. tell me it gets better. I'm a SAHM so I am constantly with him and I'm at my wits end. I just want to cry. It's like a switch flipped over night!
