Okay so I know this might sound crazy.... But I NEED HELP?

Okay so basically since I was 14 Iv felt something was wrong with my throat, sometimes i feel its way harder to breath... but only on the right side if this is possible like. Iam 17 now, and it still feels harder to breath and its always the trigger of my anxiety attacks cause I can get very obssesd with thouching my throat and checking it. Recelntly iv also noticed that if i lighty push the side of my throat it makes a clicking noise and moves, is thi normal, it really freaks me out, im scared my throat is shrinking almost. another thing is i was bulimic for about 2 years and have bad acid reflux but havnt gone to get it treated, could this be causing my weird throat eppsiodes, is there a cancer that can make me feels this way. help pleaseeee
