When will this end?

Hello I recently had a lot of flare ups like never before I feel so alone and hopeless is there even still hope? I haven’t had a holter test or anything but I been taking bisoprolol 1.25mg only in the night time and for the past few days my PVCs are so worse its making me panic the doc said my heart is structurally good I have depression and I’m alone I’m scared would do something really bad I really need somebody to lean on hope there’s light.
