Behavior problems after moving

We moved out of my Moms house in August and ever since my 3 year old gets angry and depressed over the smallest things. Hes happy the majority of the time but has random outbursts. If I don't give him the right color Popsicle he cries until he gets it. If our dog (who he usually adores) comes into his room be screams and freaks out, but other times he gets so excited & playful with the pup. Hes always been a picky eater & a lot of foods make him gag but he's gotten worse with it lately. We can't get on a routine bc he's never hungry at the same time. If I tell him To quit doing something he does it right away and busts out laughing. I've never seen him act this way before we moved. Minus the eating part. Hes always screamed while getting his hair washed and now i have to force him just to take a bath. Whenever a relative leaves he says things like "am I gonna see you again?" or "do you want to see me again?" and he says it in a sad way. It breaks my heart. The only good thing abt our move is he's potty trained now. He makes up different stories about where his pee goes which was odd to me.. He says things like "it's going to the alligators water to feed them" lol its pretty weird but I guess it's just his imagination coming into play. The anger part worries me most. I have to walk on eggshells around my 3yr old bc I never know what things will make him snap. If his cousin is using a cup or fork he wants he'll throw a fit until he gets it. He starts crying until he hyperventilates. Ugh idk what to do. Is this expected from a toddler after moving or could he have a problem? I probably left other changes I've noticed out... There's just so many and they all got bad at once. I can't even discipline him bc I don't know how I should anymore. I just hug him and tell him I love him over & over when he has meltdowns.

where'd you move to?? Do you live by yourself? That's weird, although I guess it's normal if you have never moved w/ him before. I've moved a lot w/ my kid  

we moved somewhere with my sister. we've moved three times and he's never acted like this. idk what's wrong with him /: he was too young to really understand the first few times though.

well I hope he feels better soon! have you tried sitting him down & talking about that stuff?
