Just a severe case of low self esteem?

For as long as I can remember I’ve had these days where I just can’t bear to look in the mirror. Lately it feels like those days are taking over my life. It’s not as if I look in the mirror and see that my hair is misbehaving, throw my hands up in the air, and say I’m having a bad hair day. It’s more like my face and body seem to have morphed dramatically from the day before. As if I don’t recognize my physical self because I’ve become so unattractive since the previous day. I logically realize that isn’t possible, and that it’s all in my head.
Sometimes I’ll refuse to leave the house as a result. I catch myself telling my husband that I “feel so repulsive, I can’t let anyone see me this way.” Again, lately, those days where I refuse to leave because I’m afraid that people will look at me have been more and more frequent. I’m not afraid of people or socializing, I just don’t want anyone to actually look at me.
I try reminding myself that it’s just my imagination and that no one else is seeing what I’m seeing, but the longer I stand in front of the mirror trying to get ready, the more frustrated and upset I become. I can’t even count the number of times that I’ve ended up in my bed crying hysterically because I can’t “get dressed”. It drives my family absolutely crazy when I do it and I’d like to stop. I just don’t know how to do that.
Do all women go through this at some point or to some degree? Is there something that I can do to make it better on my own, or has this gotten to the point that I should be seeking help?
