My first thought is that your gooseberry is way too close to that wall - gooseberry bushes grow to about 1m x 1m so need lots of space.
You can grow them as a cordon against a wall, but if you were doing that you'd be starting with a different shaped plant, and even then you'd plant away from the wall and slope towards it.
Walls can act like a sponge and absorb a lot of moisture, and they also make a 'rain shadow' preventing rain from falling on the ground at its base.
I think your gooseberry bush is thirsty - I'd prepare a good patch of soil where it'll have plenty of room to grow, semi shade is fine, then transplant it and give it a good watering and mulching and don't let the soil get too dry.
