i need fitness friends!

Hi

So I've been on the heavier side of the scales ever since I was a kid, and I'm now 21.
I do want to lose weight and started trying to be healthier a few years ago - trying being the operative word.
I'm 5'6 and weigh 80kg - well thats what i weighed last time I went to the nurse. I'm a borderline dress size 14-16 depending on where I shop, some places an 18!
I really want to lose weight and get to a healthy weight of around 55-60 kg or at least fit into my size 12 dress. :-(
Last year I was diagnosed with early wear and tear in my hips due to a vitamin D deficiency and asthma.
Last month my asthma became really bad and I decided it's time I became healthy
I was also diagnosed with mild lactose intolerance - I don't get severe symptoms but my skin reacts badly and I get cramps.

I'm just looking for someone out there who can help keep me motivated and start this journey with me.
I'm trying to blog my experiences as well but not everybody responds to blog posts and I just want someone who understands what I'm going through.

Thanks in advance
:-)
