Level 2 is "requires substantial support". This is where there are significant obvious impairments to daily life. You may not see emotional reciprocity, and peer relationships may be difficult. Sensory sensitivities may be more pronounced.
Level 3 is where people may be nonverbal or not always verbal. They may need significantly different communication systems like pictures. Aggressive outbursts, repetitive and narrow interests, self harm like head banging, shutdowns or meltdowns from moderate to mild stimulae are not uncommon. They will likely need supervision and may need support to consistently complete basic daily tasks like eating, toileting, etc.
I'm diagnosed level 2. What you are describing does not at all sound like level 1. Perhaps you've flipped the scale and meant somewhere between 2 and 3?
