Good for you for going to the doctor. Yes I think you should start taking this medication and read the pamphlet they give you, that lists the side affects. Just remember they list all possible side affects known to man (lol) and you may not have many. Take it regularly and you won't notice a big difference at first.

Can you afford to live on your own? If you can, then yes you should move out. I agree you should forget about the woman in Germany - it's basically the same situation you were in with your current partner, years ago - plus geographically it's way too complicated.

You need to focus on getting well and living on your own. When you're feeling better and ready for a relationship - it's better to look for a woman who's completely unattached(not separated) and someone who's independent. It will probably be tough at first because even when we're in a bad relationship, we still can miss what ever company that person provided. You never know it might be a relief lol. Do you have any siblings or family?
