ok, I will bite, lets say this is really all real.
first forget GF, dating, all that sh!t, why? you need to get a hold of yourself first, first thing first, undertand sh!t happen, being emotional will not help, you lose your job because you choose not to concentrate on it and let your weakess be seen to everyone, other problem is your needy atitude, that will not help you getting friends, GF or jobs, you need to stand alone, saying you can't be alone for long is bad not only for you but anyone around you, that is why you are failing.
with your parents you need and really need is, try to make your mom help around more, even blind people live alone, if her only problem is her sight she will need to help around, train with her so she can do what she can, being hard to do is not excuse, you can't be with then 24H a day you need to find a work to pay for things you all will need, your dad unfortunally can't do much, possible no medic will operate him or put any kind of treatment safe for betterment of life, so if you need to cry yell go to a room alone do that, let it all out, then get a hold of yourself again, you can't show weakness, doing so not only will not help you but will make people pity you if they don't try to take advantage of you.
you need to understand you GF quit, not becasue what is hapening, not because you lost your job, but because you are there feeling self pity, woe is me and all that sh!t and doing nothing to fix it.
no one can really help you if you are not willing to work for it, self pity is a annoying thing to see in a men, if you are strong at least fake it to others
