Is this Hemokatín (Vampire) race (Including all 6 Subraces) balanced with official races?

I want to see if this race is balanced in comparison to the Dungeons and Dragons Fifth Edition official races.

Hemokatín Racial Traits

Ability Score Increase. Your Charisma increases by 2.

Age. Most Hemokatín mature slightly faster than humans, though Bloodlines are simply seen as early bloomers. They then age much slower than humans, living up to 750 years old.

Alignment. Most Hemokatín born to Hemokatín are good aligned, hating to see others suffer and only drinking blood directly from humanoids when desperate. They also love self-expression, and tend to be chaotic in alignment. Bloodlines are often neutral, reflecting their human sides.

Size. Hemokatín are the exact same size as humans. Your size is Medium.

Speed. You have a base walking speed of 30 feet.

Bite. You can bite creatures as an unarmed strike. If you hit an undead or construct, you deal 1 piercing damage, rather than bludgeoning damage. If you grapple any other creature as an action on your turn, you can immediately use this attack as a bonus action. If you hit, you deal 1 piercing damage, plus 1d8 necrotic damage, and you regain hit points equal to the damage dealt. If the humanoid’s hit point total reaches 0, they fall unconscious but are stable for 1d12 days, rising on the night after the last day as a Hemokatín. They gain the Hemokatín racial traits, except for speed and size, and lose any racial traits they had before, and regain all of their hit points.

If you do not use this attack against a living creature as described above for 3 weeks in game-time, you go insane: You gain the poisoned condition, and when you take an action in combat, you must make a DC 20 Constitution saving throw or lose the action (And waste the effect being used) and roll a d4, becoming paralyzed for 2 rounds on an odd roll and becoming stunned for 2 rounds on an even roll. This effect does not extend to your Bite attack or grappling, as long as you use the bonus action allowed after a grapple, and persists until you use the Bite attack three times in combat.

Darkvision. Due to your relationship with vampires, you have superior vision in dark and dim conditions. You can see in dim light within 120 feet of you as if it were bright light, and in darkness in the same radius as if it were dim light. You can’t discern color in darkness, only shades of gray.

Advanced Grappler. Your abilities enable you to grapple much better, to enable you to obtain the blood you need. You are considered proficient in the Athletics skill when you use it to grapple, and can double your proficiency bonus with it when your proficiency applies. You also have advantage when you attempt to grapple a living creature.

Keen Senses. You are proficient with the Perception skill.

Light Sleeper. You do not need as much sleep as other humanoids, due to your near undeath status. Magic and chemicals, including poison, cannot put you to sleep, and you only need to sleep 4 hours to gain the benefits of a long rest. You still need to perform only light activity for the rest of the long rest.

Undead Fortitude. You have resistance to poison damage, and you have advantage on saving throws against poison and magic. You also cannot be infected with disease.

Sunlight Sensitivity. You have disadvantage on attack rolls and Wisdom (Perception) checks when you, your target, or whatever you are trying to perceive is in direct sunlight.

Languages. You can speak, read, and write Common, Hemokatín, and two other languages of your choice. Hemokatín is a language full of jargon, to be used among Hemokatín as a sort of thieves’ cant.
