Hello 07welale: I see this is your first post here on PC. Welcome to Psych Central. One additional forum that may be of interest to you would be the Anxiety, Panic & Phobias forum. Here's a link just in case you haven't already found it:

And then here's a link to an article, from Psych Central's archives, on the subject of OCD:

Obsessive-Compulsive Disorder (OCD) | Psych Central

You mentioned intrusive thoughts as being something that is of concern to you. So here are links to 4 articles, also from PC's archives, that talk about how to let go of intrusive thoughts:

You asked what members, here on PC, think you should do. My personal opinion would be that talking to your GP (as you mentioned) might be a good first step. At some point you may want to consider seeing a mental health therapist, a psychologist, or perhaps even a psychiatrist (if it were to be decided you need to be on some sort of psychiatric medication.) However, at this stage, I would think talking with your GP about what you're experiencing might be a good way to get started. I hope you find PC to be of benefit.
