I've raised £8000 to finally allow me to fix my body

I was a size 10 at age 18. I got pregnant with my first child then, and put on 5 stone whilst pregnant. I had gestational diabetes, and my son weighed 10lb 4oz at birth. The birth was quite traumatic for me mentally, and I was a size 16 afterwards. I've been on anti depressants for nearly the last 15 years due to the wreck my first birth left my body in, especially my stomach. Due to so many circumstances, and even though I do work 30 hours a week to support my three children, to cover the cost of a tummy tuck. It affects every thought I have and kills me to see in the mirror. Spending my whole twenties like this has made me feel like I missed out on on feeling young. I had skin to spare with my subsequent pregnancies. I was diagnosed with epilepsy 4 yrs ago, I had to quit my job because the DVLA took my licence for a year and in order to drive I must take medication for it that plunges me further into depression. My stomach affects my relationships with everyone, my confidence is in pieces, and I'm at a loss as to what go do anymore. I drastically thought of trying to cut the skin off myself so someone would HAVE to help me....the nhs said they don't do tucks for vanity. I beg to differ - this is my mental well-being and I want to be a better more healthy mum for my boys. Desperately.
