I agree with jakegarelick, a good therapist will not hospitalize you.

What matters is for you to talk.

Why would anybody not deserve to be alive? Life is fundamentally nonsensical, and our struggle / cross ( depending on how you see it ) is to put meaning into it. This is why life is at the same time a tragedy and a liberating experience.

We are ephemeral, and not this important at the individual level. Only thing that matters is not harming others, eventually doing good to others if we are lucky, and finding joy in little things ( intellectual endeavours, earthly pleasures, art, sunsets, you name it ).

If it can help, a reading that helped me when I was deep in depression in my 20's was the The Gay Science, by Nietzsche. Don't read it in one go. Keep it with you, and read a few aphorisms every day. Some three liners aphorisms from Nietzsche made more impact in my life than everything else I read combined. This book literally saved my life.

  a good therapist will not hospitalize you

In the USA, anyway, a therapist is legally required to intervene if s/he sees the patient as a threat to harm himself or others.

It's more of an imminent threat thing than "I want to die sometimes"; the latter is very common for therapists to encounter and help their patients work through. (Ideally — not all suicidal feelings can be worked through.)
