Daniil Kvyat has admitted his mid-season demotion from Red Bull to sister team Toro Rosso has made him "not so strong."
Kvyat was forced to make way for Max Verstappen in Red Bull's main team four races into the season - and has struggled for form at Toro Rosso since then, frequently coming up short of new teammate Carlos Sainz.
Asked whether having to constantly prove himself was a downside of the Red Bull program, Kvyat said: "I can't blame them for this of course, they made me a strong driver.
"Now I'm not so strong because of what happened a few months ago, but it's not an excuse, not an explanation.
"These things, in the end, make you stronger again, but, of course, the whole situation made me reflect a bit on things, and it's not easy.
"It made me stop enjoying it for a while, but now I need to get this enjoyment back and love what I do again."
Having been bitterly disappointed with his exit from Q1 at the German Grand Prix, Kvyat had a better run on race day, recovering to finish 2.5 seconds behind teammate Sainz - albeit both were well adrift of the points.
"No points is disappointing, but, on the other hand, I felt quite comfortable today in the car, even if it was difficult to drive.
"I felt like I got the absolute maximum out of the car, which is positive. There was nothing we could have done better today from our side.
"Considering all the circumstances, it was a good day. It gives me confidence going into the summer break, to be honest. I need to put things together a bit more on Saturdays, then we can be in good shape for Sunday as well."
Nevertheless, Kvyat also admitted the summer break has come at a good time for him.
"I really need it, I think me more than anyone else. I've been really draining myself, asking too much of myself, things that were not possible in the car and in the circumstances, especially when I just came to the team.
"It's easy to drain yourself, that's what I feel like I did.
"Many people who know me saw I was not quite myself for the last few weeks. I don't need anyone to be sorry for me, but everyone has these points in their life.
"[Saturday] was a low point, but [on Sunday] I feel like I made not one, but a few steps ahead so I think it's going to be much better from now on.
"I believe we should be on a good path now. I've kind of calmed down."
