PLEASE HELP :(

[SxufferingSxoul]

It’s been a week since I started taking Zoloft and yesterday since I started taking propanolol. I used to be on cymbalta and it caused me postural hypotension, which got a better in terms of dizziness, only lol. Nowadays I keep assuming that I won’t make it tomorrow, but then tomorrow comes and I’m still alive and it causes me to assume that I won’t be alive next week! The cycle goes on, MAINLY BECAUSE of these physical symptoms that CANT BE ANXIETY SERIOUSLY! First however I move when I am sat down, the centre of my chest (stomach maybe?) gets so damn tight and heavy along with the rest of my abdomen, restricting my breathing to the point I know for sure it will stop but it doesn’t lol. I can take shallow breaths but deep breaths are almost impossible and I have been reassured many times that I don’t have asthma. Which I am finally convinced bcoz propanolol would affect breathing for people who have asthma and propanolol didn’t really make my trouble taking deep breaths worse or better so phew?. Everytime I stand up I make sure I can hold on to something because my entire torso including my central chest gets so heavy! I dont know how to explain but each breath feels like it weights about a ton. I don’t know if that’s a panic attack tho bcoz since I took propanolol my heart is calm but my chest and so isnt! Eating...eating makes that feeling so MUCH WORSE! Only when that feeling is there tho, it comes and goes. So I’m wondering if the time it comes is a panic attack? Because like I said my heart is totally calm but my chest, hell no. I’m also too scared to exhale deeply because I worry that I won’t be able to take a breath again after, since each breath feels like it weighs a ton. PLEASE HELP ME! IS THIS ALL ANXIETY? IT CANT BE!
