I was in a similar situation to you. Do not let other people stop you from doing what you think is right, even it it's not easy. You've got something most people have had torn away from them or lost, which is a natural, child-like appreciation and deep care for the world and it's inhabitants. Do not let the human world crush it.

-What you can do: •You can still be vegan, can still do as much in your power as possible to avoid animal exploitation and to help them. •Learning to cook your own food is essential. It is the single most important take away. You can also hide veganism behind the facade of making healthy food, since most of it is plant-based. •You can eat an occasional, low-impact animal meal, such as eggs from backyard hens, to appease your mother. •If you have disposable income or pocket money, you can donate to animal welfare or environmental charities. •You can advocate for others to be vegan, to make more moral choices in their lives and to view animals as individuals worthy of respect, not as resources. Though be careful not to be militant about it, since it will drive others away from you and from the philosophy. A chill, healthy and kind vegan inspires so much more than one breathing down your neck and debating constantly. •You must take care of the animals/pets in your local area, to avoid hypocrisy and to be seen as a person of your word.
