Well you have made the right step by asking here. A few quick questions and I can help.
Do you have any medical problems? Are you on any medicines? Do you have any kids/other family?
Let me know and we can work through this.
I'm glad to help. What you are describing to me is appropriate situational depression. What you have gone through must be very hard and I wish I could give the magic answer. Unfortunately there is no quick fix. I would suggest the following: See your doctor about a short term prescription for depression. This can help you get your life back together. The other thing I would advise is seek out a local support group. I know you can do this because you have already taken the first step by asking here.

A natural alternative is St. John's Wort, you can by it at any local pharmacy and many people feel it helps as much as prescription medicines.
I also wouldn't worry to much about being addicted to depression meds. They don't usually work like that.
As with any medicine anti-depressants can be tought on your liver. That is why it is important to have blood work at least every 6 months.
I have faith in you. You are the one doing the work and making the progress. I'm just here to let you know you are doing the right thing.
