I think if anything when LOA has been studied and practiced with the best and positive intentions there is no such thing as illness. Cancers have been cured, sight has been restored with LOA. There is nothing it cannot achieve and manifest. Since you have just started things are still getting figured out. You have to learn to switch your reality and not hurry. I know it can be hard because we want our SP back like yesterday but how would you feel if you manifested them back only to lose them again because your vibration was negative? We can no longer allow our mental illnesses to control our lives (I used to have depression and now it's just anxiety) It is the reason my love and I weren't together. I stopped letting it control me. Everyone finds their own way of doing that. So you will too. Trust the process, don't rush it and talk to yourself when you are feeling that fear, it really helps because you are confronting it and growing instead of retreating and allowing it to rear its ugly head. Just like Veronica said it will float away but these things require work. They require reprogramming and forgiving your past, forgiving your love and moving on. 
It isn't LOA that is terrifying, it is the fact that if you didn't feel the fear, if you don't allow yourself to be controlled by it, that you might actually be happy, you won't be defined as a person with OCD. These things require strong commitment and time.
