I feel exactly the same way. I have no drive or enthusiasm for anything. I want so much for some mania to kick in so I can have some energy and get stuff done. My husband calls me lazy and asks what I want to do with my life? Huh. I tell him I just want to be happy.
I have no goals. I question myself why am I on this earth? I'm a waste of space. I don't do anything or go anywhere, except grocery shopping and dr. appointments.
I drink energy drinks, too. Sometimes I'll perk up a little at night and get in a party mood, but my husband doesn't like me drinking. And I suppose it's bad for me anyway.
I don't work, so I don't get out of the house for that. I don't have friends. We are totally renovating our house all by ourselves and my husband is doing 99.9% of the work. I do a little bit here and there but mostly I can't motivate myself to get anything done.
Unfortunately, I don't have any suggestions on how to get out of this funk. I could send my husband over, he'll hollar at you until you feel like crap that you just have to do something because he made you feel like a big loser.
