Worked age 18-34. After that had jobs here & there but never stayed because of my depression. MHMR has me on meds and i started counseling. SSI SSDI?

Been treated since about 26 for depression and about 30 for anxiety. Im 39 and have panic attacks, depression and bipolar 2 is diagnosis. Been to pyschiatrists. Now mhmr and family dr only as Ive been unable to work steady since 2014. Would i apply for SSI or SSDI? I currently also take care of my blind boyfriend with kidney and cardiac failure. Its been a year still fighting for his disability. Would an attorney be able to help me file? Who can I contact? Im in counseling for coping with anxiety but I don't see myself holding a steady job in the near future. Social anxiety is bad some days. Ive been tried on so many different antidepressants and gone to so many drs Im not sure I could remember every single one. Ive had substance abuse problems trying to self medicate but I went to inpatient rehab and I am clean at this time. Ive just always been a depressed person, no hobbies or interests.
