Depression from Metoprolol?

I know that this whole being new to AFib thing can be mentally taxing. But I’ve NEVER dealt with depression in my life. I’ve dealt with some rough stuff in my life and I always manage to stay positive. But for some reason I can’t seem to pick myself up. Everything makes me sad as shit and I always have a feeling that my days are numbered. A constant lump in my stomach like something bad is going to happen. Fuckin sucks honestly. I did a little research and it appears that beta blockers have been loosely linked to depression. Has anyone else had this experience?
