The depression that you're going through is a natural sequence to a terrible list of events. The fact that you're having a hard time dealing with things in no way suggests Aspergers or a character defect. Even if you do, you can still have a depression.
Depression is most effectively treated with a combination of medication and therapy. The combination of the two is more effective than either one alone. Signs of depression include a lack of energy, isolating, loss of enjoyment in things. Anxiety ofter accompanies depression, and there are several antidepressants which will also help the anxiety.
First: go to your doctor and get back on an anti-depressant, as soon as possible.
Next: schedule an appointment with a therapist. If you don't have insurance, check your county mental health agency for resources for those without insurance.
Then: make yourself go out of your house at least once a day, and be around people. Isolation allows your mind to wander to the negative, without reality-checking your thoughts. Human beings need other people. Find somewhere to volunteer or to interact with others in some way.
The thing is, you can't wait until you feel like doing these things--you do them now, despite how you feel.
