Dealing with low self-esteem

I have had low self-esteem for a while now. It pretty much all has to do with my weight gain over the past couple of years. I’m always tired. Always hungry. I lack motivation to do anything. Nothing fits. I can’t remember the last time I took a selfie. I don’t like for my husband to see me change. I can’t look at myself in the mirror at times.

I used to be so confident. I’ve lost touch with a lot of my closest friends because I’m ashamed that I have “let myself go”. You’re talking to the person who was the MVP of multiple sports in high school. I don’t want to see their faces of shock and disappointment.

Until about 2 weeks ago. I got tired of being tired. I am working out 5/7 days. I have started to feel a lot better– health-wise. This is the longest I have gone without drinking dark, caffeinated sodas. I have actually been drinking water. Slowly but surely the water is becoming more enjoyable. Right now I can only drink extremely cold water. I can’t with room temperature water yet.

I need motivation and words of encouragement because I’m afraid it may just be a phase. I’m just trying to be real.
