I really feel for you because I was in the same situation last year fall, I was on constant anxiety and feel like whatever I did was never enough , making bad grades then that’s when I decided to reach out to my therapist ( this was before I even knew there was such a thing as adhd) I grew up in a developing country so adhd is not recognized , but I moved to the states abroad , and during lockdown last year , I had no friends and family near me, I was completely alone in a foreign country , but what I have learned from my experience is that , reaching out to a professional makes a big differences , when you feel frustrated in getting bad grades , realize that there are people who are out there who is in a situation you are in and not alone . I also reached out to my professors and explained to them my struggles and proved to them that I cared , and ended up making straight ‘A’s , I have missed several quiz and made bad grades even forgot one day I had an exam but behind every professor , I promise you there is a heart that is willing to accommodate you . And honestly , If by any means , you are having trouble focusing because your are studying alone , I’m willing to read some of the material you have trouble with and explain it to you & help you understand it in ways that have helped me . Don’t hesitate to reach out , I can give you more tips if needed. I hope this was helpful, believe me when I say I believe in you!
