How to deal with this and not get demotivated?

Hi! I’m a senior in high school, and it’s my third year playing. I had to miss my junior year due to health related issues, but I came back this year to try my best. Yesterday my friend, who has been the #1 seed since his freshman year, asked my coach if I could be his doubles partner. I was peak #4 during my sophomore year. My coach responded with, “Really? Are you sure he’s going to make the team?” and “I already know who might get cut.”

That really confused me because I wasn’t even playing that bad. I was wondering how I can not let this demotivate me and prove to them that I won’t get cut. We have 11 boys and he’s only keeping 8. He’s deciding after seeding, so whoever ends up in the 9, 10, and 11 spots gets cut. I really don’t want to get cut because I love this sport.
