Getting emotional during sparring

Recently I'm finding that sparring is really affecting me mentally.

I've reached the period of my training where I'd consider myself to be of an intermediate level. I've had an interclub fight and am looking to have an amateur fight booked as well in K1 rules.

this has become a fairly big part of my life now and outside of work I'm pretty much always at the gym.

there're two people in sparring who are levels above me and it feels like I can't do anything do them, I can land a few counters here and there but I know that if they threw anything full power I'd be laid out on the mats.

I've no idea why I feel this way but I get so frustrated and annoyed sparring them that sometimes I even feel like crying.

it's such a stupid feeling, it's just sparring and we're just there to improve but I can't help but feel this way.
