How to Detach Myself From my Bf?

Problem/Goal: I am very dependent on my bf, to the point na nakasalalay sa kanya kung ano magiging mood ko, pati paglabas niya kinaka overthink ko (overthinker)

Context: My bf just started his career today, and I cant help but overthink. Ilang beses ko na inopen up to sa kanya pero nir-reassure niya naman ako, ayoko na mag sabi because I don’t want to be a burden sa kanya huhu. Lahat na lang ng ginagawa niya today gusto ko malaman (with pics) onting galaw lang need ng update, and ik it’s super toxic, i cant helo but overthink kasi, ik it’s an issue with my self, so guys pls help me!! and pls be kind to me, no harsh words, i am trying to be better for him coz i rllly dont want to be a burden sa kanya now that he’s slowly achieving his dreams. Nasanay lang talaga ako na natengga siya ng ilang buwan sa bahay nila and hindi siya as in lumalabas, and now super laking adjustment to not just for me, and also for him din. Give me some tips guys! Anythinggg (wag lang cheating OK, i love my bf sm) Previous Attempts: Dati kasi he used to be like me, and i used to be cool naman, he used to overthink almost everything pati followers ko sa ig, pero ngayon okay naman na siya, we talked abt it, and he said he learnt how to trust me, and i asked him howww pano niya nagawa yun, he said a lot of thingsss, peri di ko talaga alam panooo
