You're fantastic for achieving this,you have shown a good amount of mental strength here!
How are you feeling, and what are you planning to sustain the weight you feel happy with?
128lbs I think?
Look up what your best BMI is firstly.
After all of this it would be good if you gained some weight,not fat but muscles to fill the room you created in your skin by losing fat and to just be healthy having a better consumption of calories.
After this you can set new goals to keep you motivated,use your new self to do things you could not do before like hiking biking,climb a damn mountain,you can achieve so much on your own if you want to and maybe some dating might give you a new great experience.
Love is the best thing to live for.
