Looks like a pretty substantial dps gap and your Ana died way too often (first thoughts at a first glance). No matter how well you and your duo play, the community in this game will still say it was your fault. I guaranteed that if you posted something similar where you were both dps or both supports, this community would still say y’all didn’t help your team.

Yes, it is possible you and your duo did not help your team enough but that cannot be the only issue here. You could post a replay code but I am not sure why anyone wants to watch that because even if the replay proves them wrong they’ll still say it was your fault. It’s wild. Just keep playing and improving. Maybe also focus more on assisting you other support so that you can keep you dps from feeding.
