How to practise without having aversion towards life?

Before I started studying Buddhism I had desire for life and desires for more in life. That eventually led me to inevitable and immense suffering and eventually to Buddhism. Now as I practise Buddhism and as I study sutta and all I understand that rebirth is something we need to avoid by practising dhamma. We have to end this cycle of Life and Death and eventually suffering. Buddhism is a soteriological practise and philosophy which guides us out of samsara. Also lot of Buddhist suttas mention suffering as inherent and innate. Now this has led me to other end of thought spectrum of **aversion** towards life. As I learnt and understood '**craving for non existance'** is also a craving and should be avoided. But how can one think otherwise. Its either I want life or I dont want life and undertake an arduous journey towards Nirvana. How can one not feel aversion towards life if one desires and practises towards Nirvana. My question is how do I think or train mind to not have either desire or aversion towards life?
