Suggest Treatment For Bloated Stomach And Dry Mouth With Increased Heart Beats

I am 14 years old, and i am a boy, and about 3 days ago i had this really annoying depression, which went away after about 2 days, but since it did, i noticed my stomach felt full, but i got that scratching feeling i usually get when I'm hungry. My mother said i had a bloated stomach. I also had constipation. I dealt with it for a day, but when i woke up this morning, my mouth was dry, which wasn't surprising, because i sometimes do wake up like that, so i went to get some water, i usually limit the amount of water i drink because of my stomach, but i couldn't help it. This happened at like 4-5 am. I went back to sleep right after, then when i woke up, my stomach felt a lot worse, my mouth got dry again, and i noticed my heart was beating faster then normal, and my chest felt warmer. Now my mom has to wait to get a doctors appointment, which will be awhile. I also have a lot of mucus in my throat. I don't see anything right now i can use to measure my height or my weight, and my mother wont tell me because she says its not abnormal for this situation. I'm still worried.
