Will I ever leave silver?

Help guys, I don't know what to do anymore. I have like a 60% win percentage with my d.va main and I feel like I'm carrying half the games I'm in but I keep losing due to leavers or just toxic teammates. If feel like there's no right move, because when I go healer suddenly we aren't getting enough kills or if I go DPS suddenly it feels like we have no established front line or anything to initiate on. should I give up solo-queuing and just stick to queuing with friends until I'm in a higher mmr? My qp mmr actually quite a bit higher since my irl friends don't like to play competitive.

try to communicate with your teamates.
although they won't always listen it feels like in the lower ranks they listen more than half of the time if you're not toxic.
that and you say that you already carry it should be very easy to climb ranks, I feel like "elo hell" is at master in season 3 because they are the same skill level as diamonds of last season but with a much higher ego because of the title of their rank so they don't listen or communicate enough, (not all of them but the people that insta lock dps)

another thing that can help you is playing with someone, having another friend that can play healer/tank or carry on dps can really help the team structure.
