The former Made In Chelsea star, 33, opened up about her struggless with mental health issues, which were exacerbated by motherhood and lockdown, in a candid Instagram post on Thursday, August 18.
She wrote: "I wanted to have a catch up... I recently recorded a podcast for @thegoodglow.ie where I shared something, that in all honesty I didn't think I would.
"I have had anxiety most of my life and found helpful tools manage it... since lockdown & becoming a mother my anxiety (particularly social anxiety) really started to take over, consuming my thoughts leading me to feeling trapped.”
She continued: "I engaged with therapy, to try and understand where the anxiety stems from, which meant visiting some painful experiences from my teenage years in hope it would release some of the association and anxiety.
"Instead I found it really triggering & became more anxious than ever.
“After a lot of thought and discussions with my therapist we decided a low dose of prescribed medication, whilst continuing talk therapy would be the best way forward for now.”
The reality TV Star continued: "Although I knew this was the best decision, I found it difficult to admit to myself & to my family that I needed this kind of help.
"I would always encourage and support friends and family in their own mental health journey but I guess it's different when you are the one in need."
The mother-of-two also revealed that, thanks to the therapy and meds, she is now feeling like she is 'in control' of her life again.
She wrote: "It's been a few months since I started my medication and with regular exercise and sleep. I am feeling so much better, lighter.
"I can focus on being the best version of myself for my girls & Hugo without my anxiety stealing the joy from what should have been happy moments. I'm more in control and like myself again! “
She also encouraged those who are struggling to speak out, but cautioned that medication will not be suited to everyone.
She added: "Being open about mental health is so important! Life is not always as shiny as it seems here and I feel strongly about normalising these conversations.
"As a side note, medication is not the answer for everyone, this is just my experience.
"Ultimately what I want you to take away from this is that it's ok to ask for help, that whatever you're going through, however you're feeling, you're not alone and there is help out there."
MacKintosh is married to fellow former Made In Chelsea star Hugo Taylor and the pair share daughters Sienna, two, and Aurelia, nine months.
