Continue cut or start lean bulk

for context I am 17 and my height is 178cm I started my cut on October 6 2025 my weight was around 81.5kg now my weight is 71kg and in past 2024 I reached around 91kg but then got to 82-83kg and I stopped doing diet and gym and then my weight jumped to 87kg I felt really insecure and I did crash diet for 2 whole months straight I ate less than 800kcal a day .I was literally starving eating 1 meal a day and in 2 months I reached 73kg I lost muscle mass I still looked skinny fat/fat I got Soo weak I was 16 when I was doing it then after it I binged for 2 months ate carelessly and got back to 81.5kg now I am doing a healthier cut and going to gym too

I am libido is very low like I feel asexual ig due to long deficit and I do plan to continue my cut for like 30-35 days then doing a maintenance for 2 weeks then think about cut/lean bulk

I asked chatgpt it said that I need more muscle there is no point in losing more fat if there isn't any muscle underneath you will end up looking soft even now I have body dysmorphia relatives say that I look weaker(their way of saying I lost fat ig) I still have chest fat its really annoying and my waist is 33.5 inches my maximum waist was like 38 inches the area below ribs is leaner it's 28.5 inches

Soo idk what should I do I have been told that I am in a growing age I shouldn't cut for this long

my strength did improve in workouts but some days it feels very off
