Where my somatic ocd people at!?

Sometimes I feel so discouraged because I feel like I haven’t been able to breathe normally for the past couple of months and it’s sometimes hard to believe it’s in my head because it physically feels so suffocating sometimes and today my chest feels weird(not like a pain but like a sensation). I’m on Zoloft and think it helps with my anxiety but the fact that I don’t feel anxious anymore and this is still happening I making me think that it’s still a physical thing even tho the Er said I was fine months ago :/ anyone relate ?
