Hi Carly and welcome!
I am sorry to hear of this problem and the stress and worry that it is causing you.
This is a fairly common anxiety issue. Remember how in a lot of cartoons the characters would, when nervous, *GULP!* ?
Well, this is because it is a common physical manifestation of how our bodies react to stress and anxiety.
Have you talked to your parents, or another trusted adult about
this issue? If not, then I would suggest doing so, and perhaps getting some help if you feel that your anxiety is keeping you from feeling well and doing the things that you want and need to do.
In the meantime, you can try these coping skills. They are helpful in stress reduction, and could help reduce this problem.:)
