Depression crippling residual symptom.

Respected Doctors, I'm suffering from clinical depression from 6 years, After taking almost all meds available, I'm still not able to get out of one residual symptom which is cognitive impairment. After depression treatment all my severe symptoms are non existant with medicines but my ability to learn something new, to retain it in memory, to recall is not getting better. When I try to make effort, my whole face starts sweating and I feel very much unable to think and feel after that and when I try to ignore& keep on continuing studying then the stress becomes so high that easy tasks become difficult. I just want to know that is there anything/ any medicine or whatever which can help me to be like before or does depression takes away the ability to learn? I'm unable to even try for a job coz I'm unable to learn any new skill even after putting many hours into it. This can take my life in future. Help me recover completely plz🙏
