I dislike myself...

I hate how I look. I let myself get this way. I just tried on all my clothes because my husband, our parents, Friends and I have a dinner date together at a theatre place. Nothing fits me. I'm holding back my tears and I don't feel pretty at all. I've tried changing my diet and doing home exercises but nothing's changed. I'm just so disgusted with myself. Sorry for my vent. just not feeling it.
