How to deal with waswasa?

I want to seek counseling for a serious issue which is destroying my peace and ibadah I am facing extreme waswasa I often feel like hitting myself not intense but to distract its destroying my mental health and I watched multiple islamic videos to help cope with it but I am is still not able to fight it completely and I also get waswas for my family astaghfirullah like hope they die but than I cry coz I dont want anything to happen to them
