Please help me improve my SMS scale code!

Hello guys, first of all, sorry for my total lack of knowledge regarding coding and for my bad english, this is my first project. I made a sms sending scale for my beehives, the hardware part wasn't so hard with all the instructions available on the internet, but the software parts ins't that easy for me, i attached the sketch i'm using, i made it by combining some examples i found, i have no idea what i'm doing so probably it is a total fail but it's working at some level, please help me improve it, it is working very badly, sometimes i have the send the request SMS up to 5 times to get an answer back. I forgot the mention that my scale is made from one arduino one, SIM900, temperature sensor , 2 HX711 and 8 load cells. I bet that for many of you it wont even take 5 minutes to write a good code for my scale so please help me.
