Sheridan Larkman is crowdfunding for a much-needed reduction for her K-cup breasts.

For anyone who assumes bigger breasts are automatically a “blessing”, Sheridan Larkman is proof they can be anything but.

The 23 year-old mum of two from Trafalgar, Victoria has K-cup breasts which she says are impacting every aspect of her life, and not in a positive way.

“From around a E cup I started to notice the impact on my health, [like] the strain on my back and shoulders and would often try and compensate for them elsewhere,” Larkman tells Mamamia.

"I got to a K cup around one and a half years ago after my last child who is now three years old so they continued to grow after pregnancy and birth."

Having seen a GP since she was 16 years-old, Sheridan has been on the Medicare reduction list for seven years.

"I'm still unsure at why there has been such a delay. I guess it's a state by state need by need case," she says.

It's now got so bad that recent x-rays done by her chiropractor revealed she has mild scoliosis (curvature of the spine).

"If I don't do something soon [they said] it will impact me a lot more in time," she says.

As a result, Larkman has turned to GoFundMe to try and raise the $10,000 needed for a private breast reduction.

"My breasts are draining my health. I have mild scoliosis, constant back and shoulder pain and I am so tired of of dressing to try and cover everything so I don't get crude comments that I've dealt with for as long as I can remember," she writes.

"Please help me fund a private reduction to save my health and so I can enjoy life more actively with my children and hobbies without restriction."

Larkman says she gets catcalled even when out with family.

"I can go out with friends or family and often get comments like 'Nice boobs' or 'Show us your tits'," she says.

"It's not a nice thing to have thrown at you constantly they seem to be glorified for being big but in reality they are painful and a burden."

Don't believe her? Just look at some of the early comments left on her GoFundMe page, which include the remark  "Those are a blessing. Your mind is the only thing restricting you from doing anything with them."

Larksmith is hoping to go down to "at least a D cup".

"The reduction is going to greatly impact my health and the activities I am able to do and be pain free," she says.

It will also make dressing every day far easier.

"I look forward to having breasts where I can access cheaper bras and wear clothing that are fashionable."

So far Larksmith has raise $2,693 in 20 days.
