I understand you are struggling because you are doing many things you are not confident with, this is a stressful and unpleasant sensation. We want to feel challenged in our responsibilities but also we what to be sure we can do i then.
I can understand that having someone senior to guide you and, why not say, to protect you, can bring you this security you need to feel comfortable with what you are doing. And to be sure you are learning things in the right way
On the other hand, in my opinion, in your actual situation you are going to develop an alert8ng mode in your brain. You are going to collect a giant amount of problems that are going to stick in your mind. They will be itching you strongly and when you finally will find the solution, either by your own or, in future situations, with someone senior you will collaborate with, you will be extremely attentive and the knowledge will be writing in your brain like in a rock.
Having someone to guide you will teach you how this person solves this problem, you will think this is the way and will give you small space to develop your own way to do it or at least to understand that there are always other ways.
The most important skill in our profession, i think, it is not too know the solutions to everything, but to develop a powerful problem solving skill
What I would do, and I did, would be to stay on this company for 1~2 years and then move to another team with senior people to mentor you. You will be in a privileged situation to really learn from this people.
PD: your English is good ;)
