parnoia about losing credibility

im 16 and i've been a compulsive liar for as long as i can remember. i also have emerging bpd and ocd. recently i've been recording my lies and actively working on stopping with my psychologist. ive been making a fair bit of progress. i also came clean about some very big lies about very serious things (abuse, rape etc) to someone. i feel physically sick with guilt often. i understand now why i told these lies in the first place, and why i maintained them for so long. however, i am afraid of ever putting myself out there because there is someone in particular who hates me for the things i've lied about, and i feel that they will reveal what i did to anyone i become involved with in the future. i no longer maintain these lies and have not mentioned them to anyone ive met since, but i'm so afraid that i will work hard to have a successful and honest future, and that this person will knock it all down by revealing the horrific things i lied about in the past, and that nobody will trust me after all my hard work.

i am really passionate about feminism and activism but i'm a) ashamed to open my mouth because i lied about something that is such an important issue, and feel so much guilt for the ways that my lies hve hurt abuse victims and b) i'm afraid that lies i told age 12-15 will come back to haunt me and will undermine the politics that i am genuinely passionate about. i want to change my life, be a better person and be active in helping other people, but i have this paranoia that i'm going to be found out to be a horrible person and it's limiting me a lot. please help

(i want to clarify that i made a post about an abusive relationship on here, and that that was not a lie. the ex boyfriend mentioned is the person that i lied to + came clean to though, and who i am afraid of using it against me in the future)
