Chlamydia for 4 years. To normal?

I went for STD panel 2 days ago.. for the exposure i had 4 years ago. Now I have the report.. Hiv is negative, herpes negative, syphilis negative but Chlamydia trachomatis igg antibody is 2.03 which is positive which i have been having Chlamydia for 4 years. 4 years ago, after my sexual encounter i was scared.. to go for std test.. I was scared most for hiv. Then after 6 months of exposure.. I went for hiv test which came out negative.. I was depressed and stressed.. Even now. I was not prepared for tests.. I was in denial that I cannot have Chlamydia Or other std even though i felt pain on my left testicle side 3 years ago.. Since then I don't feel that pain anymore.. So I thought it's all in my head. But this recent report has scared me.. I have had this untreated Chlamydia in my body for 4 years.. And idk what to do next.. Can it still be cured after 4 years? Can i change my igg antibody to normal?This gives me alot stress.. I want to be free from this std.. Please help me..
