Hi! As a member of the GLBTQA (Gay, Lesbian, Bi, Trans, Queer - since people often identify with different labels - and their usually straight/heterosexual Allies) Community, I would like to 1. offer morale support, and 2. advise you to contact your local and/or national LGBTQA Center(s). Here is what I was able to find in Tacoma, WA
http://www.lgbtcenters.org/Centers/Washington/507/Oasis-Youth-Center.aspx (and note, I did not do an exhaustive search by any stretch of the imagination, just a very, very quick search.) I would give them a call and see what resources and ideas they have for you. It may take networking as well as contacting a variety of GLBTQ resource centers. Depending upon your age, you might also qualify for resources and programs dedicated to assisting LGBTQ teens and youth. Services might range from finding a family counselor (at low or no cost) to help you & your mom improve your relationship, to help finding a home, a job or if need be a shelter.
I hope you are up for a character-building experience, real world, not game, as that is part of what it means to be trans, lesbian, gay or otherwise "queer" in the U.S. DO know that even as this is a uniquely personal journey, you are not alone and there are networks of people who are Trans as well as "straight but not narrow" allies, etc. Yeah, this is going to require your best judgement. GLBT Centers were created specifically to assist people with Coming Out and Being Out issues. You will probably be offered a lot of advice, as well as support and empathy. Definitely take the time to research this online. Additionally, every public college campus I know of provides GLBTQ student services; even if you are not enrolled there, I would expect you'd get a friendly reception and perhaps some advice, phone numbers, or other assistance simply from telephoning and explaining your situation. I came out to myself and close friends and then family members when I was 20 (way back in 1980) and found the Gay & Lesbian Student Alliance group at my local college helpful to the process of coming out and being out.
While I am rather inundated with email at the present (and may have internet service only thru the end of Oct--we shall see--and I hate it that there's even a chance I might miss an email from you) please feel free to PM or email me, if I can be of further assistance. While it's understandable if you feel discouraged from time to time due to circumstances, keep your head above water, and persevere. Here is a link to the It Gets Better Project on youtube
https://www.youtube.com/user/itgetsbetterproject I am 55 and parts of my teens and 20s might be described as, if not hellish, then "drama or angst-laden" but I want you to know that it does indeed get better! Really and Truly! Take good care & start researching and networking! And if you are into Star Wars, May the Force be with you, young Jedi! Best wishes
PS. Definitely contact these folks:
http://www.pflagtacoma.org/ PFLAG is Parents & Friends of Lesbians and Gays (one of the oldest GLBT nationwide support organizations.) Here you will find (probably) not only peers but actively concerned parents of Trans, Gay, Lesbian, Bi youth. Many of these folks will not only have educated themselves about Coming Out but will probably know what services and resources are available in Tacoma and nearby communities.
