I think there are free binder programs still operating - maybe you qualify? It seems this forum won't let me post the urls for the applications, but you can do a web-search for them:
Free Youth Binder Program (FTM Essentials)
Big Brothers Binder Program (The Transitional Male)
(I think the last one might require a minimum $5 donation for shipping, but the first one appears to be actually free as advertised.)
I'm transmasculine myself... I think it's great to practice self-acceptance, AND sometimes the dysphoria can be so intense you need something to make it go away. I never liked the standards of beauty forced on me as a "girl," and it's unfair that I'm expected to just trade that in for a new set of (masculine) standards of attractiveness. That said, being constantly misgendered drains so much of my emotional energy, and I need some reserve of that in order to function.
One thing I wish someone had told me before I started binding was how much it would affect my chest tissue. Now everything in that area seems more obvious than ever.
Anyway, it seems like you've done your research on the health risks, and probably know the basics - never use an ace bandage or something too small or that doesn't stretch enough, never wear a binder when sleeping/exercising/more than 8 hrs/if you feel out of breath, always cough after you take it off, etc. - so only you can decide what's best for you.
