I'm so sorry you're feeling like this. For what it's worth, you're not alone—I'm right there in the same boat with you. It's both situational and brain chemistry for me. My psychiatrist is not doing much to help me anymore and I just feel so hopeless
But know that everything is temporary, and things can only suck for so long before things inevitably HAVE to start to look up one day. Have strength and patience, and may happiness and peace come to you soon.
