I'm 18 and I've been diagnosed with anxiety and it's really ruining my life. I often get panic attacks, I can't really breathe normal, like, I have shortened breath, I feel like my heart beats sometimes too fast, sometimes too slow, I get sharp pains in my head, sometimes a shooting pain, sometimes a light pressure, I feel very weak and I feel like I don't have enough air to breathe. I sometimes think I'm gonna throw up but I never really do, I just get that feeling. These things are really making my life miserable, I can't live normally, I can't have fun like all the others normal 18 years old do. Do you have any advice that would help me to stay calm while I get this attacks?
