This started almost a week ago randomly I just started to feel sad all day and crying constantly which never had happened before. The next day comes and I can’t think straight my mind is racing I get cold and shake and sweat I just keep thinking negative things I couldn’t even eat the first 3 days of having this mental pain and I’m scared I’ll have this super nervous feeling forever. I’m not myself since this started idk what to do. I look at things differently in a negative way like I’m alone I’m just really sad and feel I have no idea what to do or if this feeling will go away. Can someone tell me what tonight have caused this and if it will go away?
