Does therapy really help?

So like does it? bc I was thinking of doing it in a few months or so like don't get me wrong I understand it's not going to fix all my problems or anything but I thought it might help to talk to someone about my problems and unpack all the mental abuse and trauma? ( not 100% sure if I have trauma or not another reason why I want to go to therapy) my parents caused me to have through my childhood and even now And I'm not dumb I know what my parents especially my mom did and said to me when I was a kid and even now is not healthy and normal behavior but idk why whenever I start to think about it as abuse or anything I automatically have thoughts like wow i'm so ungrateful or i'm just being overdramatic my parents do everything for me and i just basically start making excuses for them and start putting myself down it was so bad at one point i would just repeat the words it's not abuse and i'm being overdramatic in my head over and over again until i started to believe if you get what I mean and tbh this is also one of the main reasons why i want to get therapy so i can get validation from someone else that i'm not just making this all up in my head um but anyway what do you guys think?
