Sorry to hear that you felt so low: I have times like that and I know how awful it feels. It makes you despair totally. What's the point in anything cos you'll only muck it up. I envy those who are blessed with a belief in themselves, life seems so much easier for them. However......I have come to realise the following
1. some of those who I envy are maybe not so good at everything; some just cover up how they feel more than I do and some, even celebs, do have their low times too......and I am good at some things too. ( just not too good at loving myself)
2. I am actually more ' normal' than I think I am - sometimes there doesn't seem much to support that- but then I am hard on myself.
3. If I just accept that it's a really bad day and as others have said, be kind to myself until it passes, tomorrow is generally better: so don't make any rash decisions on the bad days!
4. We really do create our own futures and it all starts in our thoughts, our minds, our imaginations. So it really is possible to live the dream- just get dreaming!
i hope your feeling a bit better.
