Aggressive lovebird

[Tula the lutino lovebird]

New to this group , I have a lutino lovebird about a year and a half old . Is very aggressive . It has attacks me and bites and hold on . This is very painful and leaves bruises and scares me . She is not hand friendly and won’t even step up . She does engage with me in some positive ways . I owned to conures 40/years ago ( Patagonian & half moon ) both were hand tamed and never was bitten . Wonderful birds and loved the companionship . I am so upset that I am unable to have the same relationship with this bird . I got it at around 4 months old . I just need advice as I am at a loss how I can give his bird a wonderful life like I did my others .
