I think many people feel very similar when starting a therapy. Well I definitely do.
Like I´m stupid for needing help, my problems are not big enough, the T is waisting her time with me because she could be helping people with "real" problems. She surely has to laught at me under her understanding mask face. And that I´m overdramatic and so on.....I nearly quit after the 4th session because of these feelings. What made me change my mind:
The thought of my future children and the baggage I may pass on to them
the thought of my fiance who deserves better and also my T saing I deserve it too.

So I wish you the best and I hope soon you will also feel you deserve it.
