Amber..first u need to take care of urself.. be more strong... u have to see a docter..for sure.. so that u have strength to fight it out.. or to think how to resolve this issue.. If you are depressed then now one can help you..

Try to divert your mind..go out to the malls.. or join some art class or music class..

and atleast for few days talk less to your mom..she may start realizing the situation..

now since your Fiancée is feeling bad..Let him try to find options to make ur mom happy find option were he can say sorry and make her feel that he has realized mistake..

Hope things will be better..

God Bless you..

Dont lose your hopes.. be more strong.. Its life.. up and downs are always there.. dont depend on medicines..
