Anyone else on here have a high needs child?

Hey all, I'm a FTM and a SAHM. My boy is almost 1 years old. He is the love of my life, sometimes I wonder how I even lived without him for so long!! Having that said, he is such a handful. I wouldn't say he is the full extent of high needs, but he is close. He screamed in the car every time until 6 months, now he will last like 15 minutes. He cries a lot of the day. If anything goes wrong or upset him he can become inconsolable. It's hard to just go out places with him, he doesn't just sit. He finally will ride in a cart every now and then. People would ask when he was an infant if he would just sit in a baby carrier lmao. He won't just, sit on your lap or anything like that. I have to hold him a lot to calm him down. Sometimes I feel alone because every one I know has calm easy babies and they just can't relate to how much more difficult this makes everything for me. All you want is a happy kid, and he is, he just is upset a lot too. He has bad separation anxiety, I've never been away from him for more than 3 hours. My mom has even told me he is the fussiest baby she has ever known. He has rarely allowed someone other than me to feed him a bottle, and he will not go to sleep for anyone but me. I just want some kind words or something to talk to honestly, I hate feeling alone.
