Hello Fighting a loosing battle,
So you are 16 feeling stressed out and a tomboy that hates wearing pink, purple and wearing skirts. So who likes wearing pink anyway? And what is wrong with being a tomboy? If I could offer you any advise it would be to tell you to pay attention to the caring qualities you seem to have as evidenced by how you cared for your father and the fact that you love animals.
You are 16 and beginning to develop who and what you will become as an adult. Don't miss this opportunity to become all that you can. As cliché as this may appear, purse your education! Talk to a guidance councilor at school and determine the best education path for you to take.
You say that your stepfather was fine with you until you started developing your own style. Well I say so what! You are 16 and your "style" is already determined and nothing that you need to justify to anyone but yourself.
You feel that your mom is not involved in your life and at times you fear your stepfather. I would say that perhaps you should re-think that. Your mom has been involved in your life for 16 years and that means something. If in fact you do fear your stepfather talk to someone about that. There are many people to help you; you just need to let them know.
In closing, be good to yourself pursue education and if you really do have 60 something animals, do you think that may be too many animals?
