A good relationship consists of two elements, the feeling of excitement and novelty on the one hand and sustainability and reliabeility on the other hand - you just have to find the right balance.
You may be confronted with principles that put your plans upside down. Don't let yourself be drawn into emotional discussions but rather find people in your team who support you.
Your nerves are strung to the breaking point. Take your time and make a plan how you can manage to allow more time for yourself.
