Difficult to say much from a forum post... errors in self perception are probably a large part of the problem. I don't think you have a motivation problem. You seem to start lots of things. I have a motivation problem. I haven't started anything (let alone an actual 'startup') in a very long time.
One thing that strikes me is how long you last with what ever endeavour you undertake... 1 - 2 weeks is very short, especially for a relationship. I don't think that is enough time to genuinely lose interest. I take this to mean that either you didn't really want to do the thing in the first place or are afraid of something.
I don't think medicalising the issue is a good first option, as other people have said. You describe some depressive-like features such as hopelessness, loss of enjoyment, social withdrawal, weird dazes... but once you label this as a disease, it becomes very difficult to deal with it in other than a medical fashion. Having said that, if you are reading about suicide, I would get professional help.
I don't have any particular advice. It may be that entrepeneurial pursuits (which are open ended, with ill defined goals and little feedback) are not the right thing for you at this stage of life. I would also suggest you try something which places no pressure on you, and isn't encompassed by the failure cycle you describe. An example would be some sort of volunteer work, or a (team) sport/hobby. (A startup doesn't count as volunteer work.)
