Feelings are not Stupid - They are what they are feelings - sometimes they are indicators of things in our lives that need attention. There maybe some depression, physical problems like thyriod issues, have you seen your family physician?
If I feel down for a day or so, it may be normal feelings, but if it last longer than that there maybe some other contributing factors.
Don't discount your feelings - they maybe telling you that you need medical care or some special pampering.
Hope that you are able to find out what you need to feel better soon,
Hugs to you,
Rita
