Hi , I have been playing chess since April 2020 . I reached 2000 on this site after around 2 years and participated in a tournament in which my performance rating was around 1600

 But for the past 6/7 months I haven't been able to play/study much.

Now I want to return but I think my playing level has decreased, any suggestions for that?( Also I REALLY struggle in the opening , I have bought courses , the white course was fine (wesly so e4) but the black course didn't really help me ( especially I don't know what to play against 1.d4 ‌‌, both the QGD and Grunfeld feel uncomfortable.)

Thanks in advance
