why do i get so nervous watching soccer game?

why do i get o nervous while i watch soccer game when it's finals for example champion league. last champion league i got so nervous i thought i will have heart attack my hands started been very numb.

i go for real Madrid and it was semi finals BVB vs real Madrid the last 15 minutes we played very good we almost won we had to score 3 goals to win and in last 10 minutes we scored 2 and i started getting so nervous also i had panic attacks i thought it's the time i die it was so scary for me i love watching soccer games but i also use to suffer from anxiety and panic attack at that time. and from that day i am afraid to get over excited and have these feelings back. i'm thinking of watching it with mates a group of mates better so i feel more safe. we have match tomorrow at 4:45 am and i am nervous about it afraid to get that feeling again the last minutes make my heart rise and my hands numb. we haven't won the champion league in 11 years so i was 12 years last time we won champion league we are the best team in the world but only champion league it has been hard for us. i get so excited and nervous afraid to lose or they score.

how do i get rid of this. last time i was trying not to think of the game and go walk away but i did and did some breathing and it worked a little bit but when i got in to watch he game i was nervous again. help me this feeling is killing me i want to enjoy it not scare of heart attacks when my heart rise. please help me what to do.
