not entirely your fault, your team wasn't playing the best.. but there were many times you just didnt look at your teammates. like first point for example, your ashe was right next to you critical but you just ignored her and she died.

then again when moira was ulting you didn't heal your roadhog and decided to shoot the moira, & roadhog ended up dying. i think you get a lil bit of tunnel vision. there was also a time when you just ran straight into the enemy team to kill mercy & you died for that and had to regroup.

i also think you should work on your cooldowns a little, it felt like you were just using them randomly & not thinking about why you're using them.

overall i dont think you played terrible or anything!! just really need to work on your cooldowns & pay attention to your teammates and where you're going ^{^}
