I just confessed to my crush and she responded with this, what does it mean?

thank you for understanding how i feel though, if im being completely honest you are not bad looking at all and have a wonderful personality, nothing is wrong with you. maybe we can try something in the future but i don’t have the right mindset that im afraid will mess up myself and affect others if i got myself into a situation like that again, nothing is wrong with you and i don’t want you to think that at all, i just don’t have a strong enough mental state to be in a relationship at all
