Last night (yes a Tuesday night) my friend came over for dinner and drinks. Far too much wine was consumed and not enough food was eaten. I am so so hungover today and literally feel like crawling out of my skin. I am so depressed and anxious, I didn't even do anything wrong. Just yesterday I was feel hopeful about life and excited for the future. Today I feel scared, hopeless and generally negative about my future and a voice in my head keeps saying, 'you fucked up, you're not going to be able to reach your goals etc etc' (related to masters course I'm currently doing).
How can I go from feeling so happy yesterday to so miserable today? I usually get 2 day hangovers and I am in uni tomorrow. I have quite bad social anxiety especially sitting in a room with people I don't know too well and expected to contribute to a conversation. I have been managing quite well and was feeling motivated and proud of myself but today I just feel like I'll not be able to complete the course and that I've fucked everything up.
It really doesn't just feel like the hangover talking. AIBU and will this pass or have I fucked my life up??
