Desire to stay fit

I just want to be skinny, I just want to be able to wear what I'd like and be happy about it! I just can't seem to do that so much. It makes me feel so insecure & I'm trying to lose the fat I have & don't need by exercising but sometimes I have those days where I'm like 'Why am I trying?' & it's so weird. It brings me down so much, and I don't want to go back to being depressed, I will not. Many people aren't lucky by getting out of depression like me, so I will fight to stay strong. I will not bring myself down just because I want to be fit. I will not allow it.
I will achieve what I want by being strong.
