I'm a 14 year old male and ive had anxiety all of my life 

Normally I only get anxiety before school or when I'd have to do a speech or something like that and i would never have panic attacks but for the past 2 months i've been getting really bad anxiety and panic attacks. Almost every day i get heart palpitations, chest pain, shortness of breath and almost every panic attack symptom and i think im having a heart attack. The only time it stops is when I'm doing something that distracts me (like talking to friends or playing video games). I been trying to go to the doctor since it started but i haven't been able to book it yet because I just moved to the uk. What can i do to stop it and also has anyone else gotten symptoms like mine? please someone help i've felt so bad recently.
