Guessing from your profile you feel some guilt for feeling this way too. You are NOT guilty! Being tired and depressed is something you cannot help. Feeling guilt or shame for that adds to it. So, give yourself the freedom to feel as you do! Give yourself the freedom to have bad days! Give yourself the freedom to be you. It is so much easier to crawl back out of the despair when we do not feel terrible for being in it. If you are not being given this freedom by those around you - self advocate!
