very fussy baby

so my babe is 7 months. He has always been pretty fussy. He will play for a little while and then cry, he cries sometimes out of no where, he is kinda unpredictable.He has reflux too, I thought he had colic for a while, Dr said no. Tbh I wanted any formal reason for the fussiness, but I'm yet to find one. Dr says it's just his temperment. He always wants to be held, I can't put him in a stroller or cart. He cries forever if he is tired, seeing your babies fall asleep while playing absolutely astonishes me. He screamed every car ride until 6 months. Alright having that all said, he is the love of my life. I love him so much it hurts my soul. I hate this post, I hate complaining, he is perfect he is a blessing. He is beautiful and when he smiles or laughs, my heart melts. I find myself guiltily feeling jealous at times though, other people have easy babies, I'm nervous to hang out with people and get judged by how fussy he is. All in looking for is support, anyone else out there with a similar child? Are there GLOW groups for fussy babies? I just need support sometimes. I'm hormonal now anyways, I just feel like I'm the only person going through this sometimes.
