I've been diagnosed with GAD and OCD two years ago and somehow, I've been managing my anxiety attacks for more than 5 months now, which Im very proud of. 
But, these 2 months everything has been absolutely great in my life, I've had so many good things happen to me, yet I get anxious about every single one of them. I get anxious when I'm happy. It's almost like, my brain is telling me I don't deserve all this happiness and peace and freedom I have right now. I doubt everyone who I KNOW that cares and loves me, I have intrusive thoughts that ruin my entire day and sometimes sleep as well. 

I've had even worse intrusive thoughts and I've managed to make them bearable and they occur less now, but Im scared of them going back to the state where they would literally take over my mind. 

idk what to do. I know I have to just keep going but it's so hard, thinking and feeling that I can't enjoy good moments in my life because I'm anxious that 
a) something's gonna go so wrong that it will literally break me into pieces
b) I do not deserve to be happy and I deserved all the suffering I get daily

I can't even remember my old self who was capable of enjoy things and that makes me sad
