Hi, I'd like to help you with your question.
It sounds as if you may be suffering from anxiety and a major episode of depression. I agree, medication is a good idea in your case until you can be treated by a therapist who can help you work through your feelings and help you feel good again.
Although your GP can help you with the medication, you need someone to do a full evaluation to see what diagnosis you have then prescribe the appropriate treatment. Here is two links to to help you find a doctor in your area:
You should also contact your insurance company and find out which psychiatrists they cover. They should have a listing for you of approved doctors. Sometimes you can find the listing on line as well so check there.
If you find yourself feeling any worse or you feel you cannot wait to see a doctor, report to the ER for an evaluation. They can see you to determine if you may need a short hospital stay to stabilize you. If you are admitted, they will do a full evaluation and assign a psychiatrist to your case. They will also set up follow up treatment and provide medications for you.
I hope this has helped you,
