I requested, my mom wants to marry me, but I feel scared

[SintoDinto]

In my culture (the united states) and even in the muslim population of youth i grew up in here in the states, and increasingly abroad and including in my parents' country of turkey, people are getting married later, and people including my therapist say marrying later is better for marriage success, even academics.
I seem to be getting a handle over my porn and masturbation habits, and I confessed to my mom I feel overwhelmed by my sexual desire, and feel lonely at times, and don't want to fall into sin, and want to get married for that and other reasons, and she agreed to marry me as soon as possible when i was ready (she said she would get be ready, as she has been doing she says), and says I dont need to complete a bachelor's. just my associate's in a several months and get good employment while in school and after school, and she even said she would pay for my wedding before.
(wow, my mom's awesome, now that i think about it).
i turned 22 recently.
but i worry based on conventional wisdom i would cause a divorce, also due to my lack of an education.
can any elders or mods give advice? i dont trust myself, and my mother and some elders in my life like my therapist admit i have low self esteem deep down. that may be it. mods, feel free to delete this if this is not appropriate, but please dont ban me for repeated threads, but i feel its appropriate since my mom and i discussed getting married soon.

I actually had an istikhara dream interpreted by a well versed sheikh, he says to get married.
