Looking at her wiki, it may go beyond the drugs, suicide etc.... I never knew this, but her wiki says she's also got long time mental/insane issues. 20 years ago, she did some crazy thing walking on foot to a random persons house acting like they are best buddies. You dont get that from ecstasy pills.
On August 19, 2000, Heche drove from Los Angeles to
Cantua Creek in a
Toyota SUV.
[95] Heche, who was wearing a bra and shorts at the time, parked the car and walked 1+1⁄2 miles (2.4 km) before reaching a ranch house.
[95] The house owner Araceli Campiz, who had seen Heche in a movie, recognized her and let her in.
[95] After drinking a significant amount of water, Heche "took off her Nikes and said she needed to take a shower."
[95] Campiz assumed that Heche was not under the influence of alcohol or drugs, but Heche later revealed that she had taken
ecstasy.
[8] After taking a shower, Heche entered the living room, asked for a pair of slippers, and suggested that they should watch a movie.
[95] After half an hour, Campiz contacted the
sheriff's department.
[95] Heche later told the deputies that she was "God, and was going to take everyone back to heaven in a spaceship." She was then taken by ambulance to Fresno's University Medical Center and admitted to the psychiatric unit, but was released within a few hours.

Heche stated she was "
insane" for the first 31 years of her life, and that this was triggered by being sexually abused by her father during her infancy and childhood.
[96][97] In a series of interviews with
Barbara Walters,
Matt Lauer, and
Larry King to promote
Call Me Crazy in 2001, Heche stated on national television that she created a fantasy world called the "Fourth Dimension" to make herself feel safe, and had an alter ego who was the daughter of God and half-sister of
Jesus Christ named "Celestia", who had contacts with
extraterrestrial life forms.
[94][98] Heche said she recovered from her mental health concerns following the incident in Cantua Creek and had put her
alter ego behind her.
