Please help

I have a 2 and a half year old son. I want to start by saying that he has almost always been an easy going baby and toddler. Just like any other kid he of course has had his share of tantrums but overall he hasn’t really given us a hard time daily. Well the past 2 weeks have been a living hell. Since the moment he wakes up it’s screaming and yelling. Whether he doesn’t like the toy I give him or the food I put on his plate or if we have to leave the museum or the park. It’s pure screaming, throwing, kicking on the floor. I am not use to this and I have no clue what to do. I try to hug him and console him but it makes the tantrum worse. It can be over the littlest things. He use to just listen if I say pick this up or that. But today I asked him to pick up his apples that he threw and he completely flipped out. Im losing my temper and catch my self having to walk away when this has never happened before. Can anyone please help me? What am I doing wrong? How can I help him through these feelings? I wanted to have baby #2 and now I am terrified. It’s only been a few weeks but I’m a SAHM so tantrums that never seem to end are causing me to have my own meltdowns at the end of the day.
