I've wanted a breast augmentation for ages, the only thing holding me back is the concern of breast implant illness

Unfortunately, you have not provided photographs or told us your bra size. However, you have an alternative to breast augmentation. You can undergo a breast lift with fat transfers. The symptoms of breast implant illness may occur in women who have never had breast implants as well.

According to the FDA , the risks of complications or chances of getting breast implant illness is 1%. Only possible complications that breast implants can cause include are breast pain, changes in sensation to the breast and nipple which are also very rare.
The decision here is completely up to you . However, risk of getting breast implant is extremely rare. Good luck
