I'm getting over things like how to stop overthinking and ways to stop anxiety, but there's certain negative individuals in my life I can't exactly 'get away' from or 'ignore' why? because I don't have that much power yet and they get fucking tenacious when I hide, so how do I build better resilience? Not let their words get under my skin, or keep my mind free from manipulation? I'm pretty damn set on my goals in life and they want to stop them from happening, issue is I have a soft-heart despite my outward bluntness and I can get influenced easily. please help, I've already tried talking to them countless times but they're just as stubborn as me and will never change their views, neither will I because I value my life's happiness

Hey!

It's probably not going to be much of a help, but it might lead you into the right direction.

Try reading "The Subtle Art of Not Giving a F*ck" by Mark Manson. It was honestly a good, entertaining read and you might actually learn a thing or two from it.
It's been way too long since I've last read it and it's been a gift to some highschool friend of mine, but at the time, it helped me get my act together.

If I had to sum up a couple lessons I've learned from it, it would be to take responsibility for mistakes, even if you have not caused them, and to stop letting unsolvable problems bother you.

I hope you get you fix your issues soon.

B94 It sounds like you planned your Life but the question is Why Worry what "Certain Negative individual's" think of you because of what "YOU" Wanted from Life. If you Made a Life's Checklist Ex. Finish School, Go to College of your choice "Full Tuition" and Picked a Job that you enjoy then Who cares. Hell Even if you started Streaming and made it into the Big Leagues Well Fudge Those Certain Negative individuals Because It's Your Life's Happiness Not Theirs and Live the Way You Want. Anyway I Hope it Helps Somewhat.

I personally don't know how to force one to not give a shit but a good start is a role model I think, use their reactions as a case for yourself, this can use your easy-to-influence mind as an advantage, being rigid means you'll fall behind, being moldable lets you stay new and fresh.

Just as a point of warning, do not idolise the person you think of as your role model, it is usually fine with fictional characters but for real people, it is a big mistake to idolise them. Human beings aren't perfect, they will most definitely differ in opinion from you at some point, at this point move on and acknowledge that you think different, don't become a living copy of your role model. In the end, you must be yourself and stay yourself, change according to your experiences, not due to what some guy says.

It may not help right away but if you truly want to stop caring about outside things. Start today by saying "it is what it is" that little five word phrase. Is the key to being a go with the flow type person. If something happens that you don't like or didn't expect/want to happen? Well it is what it is, you tell yourself that enough and it will come easier every time you have to say it.
