Hi Vagas,
The answer to your question is all about you. How do you feel about yourself, internally. Are you prepared for an absolute life changing, mind bending experience. Are there ANY skeletons in your closet. Can you honestly look your self in a mirror and say I truly know myself from the very top of my head to the souls of my feet; without the slightest doubt. None whatsoever? Do you know, intimately, your sexuality, and I don't mean have you been sexually active. Can you without a shadow of doubt, say you are heterosexual, bisexual, homosexual?
Do you have the slightest doubt about any aspect of yourself? If there is even an inkling of not knowing an answer to any of the above, well then, you need a therapist.
Transition in its totality will test EVERY part of your existence, either now, or with compounding interest at a later time, which may be just the initiative needed to push you over the top and into places nobody wishes to go. As has already been suggested, friends may not always give you unbiased professional advice.
A therapist is not going to hold your hand. A good one will help you to become the very best you can ever be. Even with the little you may know about yourself presently, is only the tip of the iceberg by the time you've fully experienced transition, and good therapy will set you up to know how to deal with the new horizons that you'll confront. Do not underestimate the changes that will occur.
You need to remember that (from memory) 18% of post op woman still commit suicide. I'm not sure of the figures for men. When you consider you are literally turning yourself inside out, if you are still carrying baggage from your former self, you are not treating yourself the best way possible, and increasing the risk of turning a magnificent journey into something you may not totally enjoy.
What price are you prepared to put on your self? Transition is not something you can 'nickel and dime'. It's not a DIY process. Do you consider yourself priceless? In answering these questions, you'll know what has to be done.
Be safe, well and happy.
Lotsa huggs
Catherine
