for the first thing there aren't any consequences for using the cheat menu. it only has a risk to break a save if you grab something you're not supposed to have because it can cut off certain story events because you need to not have the item for those story events.
and the second thing, I'm sorry you're going through this. it's prolly gotten even harder than it was originally because of the AI bullshit lately but just know everything should take a turn for the better eventually. life usually comes in waves of good and bad, sounds like you've been through the ringer so you should get some good luck soon :) it's also no problem sharing this, unless you're trying to use the comment section/fan base of this as therapists. we are horny gay furries with a lack of morality that could frighten anyone lmao. however, as MarcusVinicius said, you should join the discord! don't try and spam art promotions as that would get you banned, but you could make some great friends who might be able to help you out with things!
also, neither is exclusive, you can be an amazing artist and still enjoy the game. some people I follow on twitter who do drawings and animations I fully believe could be in an animated film worth like 2 million play this game and are plenty caught up! you just gotta know the line between too much playtime and balanced playtime. don't play so long you can't do your job/work on getting better but don't think you need to do nothing but practice/do work and play when you wanna. also just know I and prolly quite a couple other people are rooting for you to succeed. gl on your journey!
