RJ Mitte's devastated sister pays tribute to 'my other half' after breaking down in tears at his memorial

RJ Mitte's sister Lacianne Carriere penned a shattering tribute to her late brother while promising to try her best to heal.

The Breaking Bad star, who was diagnosed with cerebral palsy around the age of three, died by suicide on October 12 at age 34 at his home in Brownsville, Texas, leaving his mother, Dyna, 61, and his sister, 22, devastated.

'There are just no words,' Carriere wrote on Instagram alongside a series of sweet throwback photos. 'You were just here. Your strawberry Fanta was still sitting on my coffee table when I got the call. Life hasn’t felt real since then.'

Carriere expressed that Mitte had been a father figure to her, as she had done at his celebration of life last week where she delivered a tearful eulogy.

'RJ, you were my everything. I just lost my other half. I lost my brother but I also lost my father,' she went on.

'Every single aspect of my personality is because of your influence. My music taste, my film taste the video games I love. Because of you I am a collector. You taught me that even the smallest piece of paper can be a precious memory later on.'

Carriere continued: 'Since the phone call I've been sitting around with your closest people almost every night sharing the craziest stories that could never be said anywhere else and god that was just you. You were the life of the party, coolest guy that we all tried to keep up with but never could. You made me, me.'

Mitte's sister touched upon all the things they could have done in life.

'We had so much more to do, so many more memories to be shared and I don't know if my heart can ever be whole again after losing the biggest piece of it,' she shared.

'I just really need my brother right now. You would put on some lofi music and tell me to get up and go sit in the shower, how it always makes you feel better.

'I know you're telling me right now that I'll be okay though I don't know how I will. But I promise I'm going to do my hardest and I promise your love will always live through me until the day I see you again.'

Carriere concluded: 'I loved you completely. And you loved me the same. That's all. The rest is confetti.'

This comes after Mitte's younger sibling broke down in tears while delivering an emotional eulogy at his memorial service on October 16.

The service was held in Brownsville, Texas, and during the speech she openly wept as she reflected on their amazing bond. She shared how he stepped into a father figure role for her after their single mother was paralyzed in an accident when Carriere was an infant.

'RJ Mitte was my older brother but I not only just lost a brother, I lost my father,' she said.

'My mom was a single mother and when I was two weeks old, she was in an accident that paralyzed her from the waist down for the first few years of my life.

‘And my brother immediately took on the father role. I don't have many words that I can put together but all I can say is that every part of me is RJ,' Carriere stated.

The actor lived with cerebral palsy his entire life after being diagnosed around the age of three and went on to play Bryan Cranston's onscreen son Walter, Jr. in the hit drama Breaking Bad.

His mother, Dyna, spoke to The Hollywood Reporter about the tragedy and admitted 'there were concerns' about his mental health but she encouraged him to seek professional help.

'It was more about the conversations we were having - not just with me, but with his team and friends,' she said.

'There were concerns. That's why I encouraged him to talk to a counsellor. I told him to talk to a therapist and share his feelings and how he saw things.'

Breaking Bad's Bryan Cranston shared in an Instagram post that he was in 'deep despair' over the death of his TV son.

'I met him when he was only 14 years old when he was cast as Walter White Jr., a part he played with such joy and enthusiasm,' Cranston wrote.

'Born with cerebral palsy, he never - ever - allowed that challenge to be an excuse for anything. He met the demanding shooting schedule head on with great determination.'

Cranston went on to reveal they were in touch only a 'few weeks ago,' writing: 'All that promise and potential now is such a loss. It is especially devastating to hear that he took his own life.

'Why? We were texting each other just a few weeks ago - figuring out when we could meet for lunch. I don't know if that lunch would have changed his future.

'But I do know that I loved him, and thoroughly enjoyed being with him throughout the years on the series, and after the spotlight on Breaking Bad dimmed.'
