Bladder issues :(

Had a telephone consultation with the doctor yesterday regarding all of the problems I have been having the last few weeks, he was adamant that its nothing to worry about and has put me on sertraline 50mg.

I am trying to take my mind off of it but I have been having this bladder sensation which is just so uncomfortable :( the only way to explain it is that it feels like something is pushing it? Like pressure which makes me feel like i need to toliet ALL of the time 😭 has anyone had this? Its been going on for 3 days now and I'm starting to panic again! Have been drinking water to try and clear anything that might be causing it but no relief yet. Thanks for reading
