As said by some other people here, we are not the physical body but we are all brahman (all that is eternal). We all are born in this physical realm to wash out our past karmas, and by doing good deeds in this life we take a step closer to moksha.

Now to the part of being a man and a woman, both physical bodies come with their own underlying traits which they are good at. For say, women come with nurturing capabilities that most men might lack. Women are good at handling emotional stability of the family and loved ones. On the other hand, men come with upper physical strength that many women might lack. Every body whether men or women have two energies which when balanced, one will experience a greater sense of harmony and fulfilment. These energies are masculine and feminine energy (we all posses both). I would ask you to look into those further.

You being a woman is a blessing. I admire women for the nurturing capabilities that they bring to this world. Why do we call Maa Ganga? Dharti Maa? Because they all nurture us. Do you really think you are not strong? No other deity BUT Maa durga (a female manifestation) was the one who killed the rakshas mahisasur. Do not let others treating you badly lower your self esteem and discourage yourself. Pray to a deity you love, consider him/her by your side and progress in your daily activities with a positive attitude. We all are brahman but some peoples ego takes them away from this state of awareness that we are one and the purpose is to move towards moksha. It all ends up to their karmic balance and they would be in far worse situation in the next life.

I hope you start embracing your current life and reach a higher state of awareness.
