So tired of being fat...

I'm so disgusted with myself. I'm so tired of being fat. I'm so tired of feeling myself jiggle when I walk.

So here's where I need your guys help. I've gained so much weight in the past year. I've really just let myself go. But my biggest issue is I have no motivation to do anything. I have every intention of working out when I get home but as soon as I walk inside I'm overwhelmed with tiredness. Plus I feel like I don't know what I'm doing.

I just need some advice on dieting and working out.

Below is what I looked like about 2 years ago and what I look like now. And I'm mortified. I hate myself. I feel absolutely hideous.
