It's hard to tell without meeting you personally and talking thoroughly and perhaps doing some assessments. The symptoms you list could be ADHD or depression, or some of each. ADHD and other psych disorders are often comorbid, such as ADHD + depression or anxiety or OCD. Are you an adult? Are you willing to take psych meds? Since you do have some depression and anxiety symptoms, a starting place might be an antidepressant that also has efficacy with anxiety and ADHD. Venlafaxine comes to mind.

I hope you can visit a psych provider soon and get a face to face assessment. Best of luck.
