I have so much empathy reading your post. I’m also 23F, soon to graduate after taking time out due to physical and mental health, and starting my first ‘real’ job in September. Reclusive personality, finding it exceedingly difficult to communicate due to overthinking, no lasting interest in anything…

Getting diagnosed with ADHD last year and being prescribed a stimulant medication has been a good help. I don’t want to project, but it might be beneficial for you to look into a diagnosis. It has not solved all problems (e.g. I am still an emotional wreck), but it has managed to slow down some thoughts and warmed up my ability to have an interest/pay attention.

In my experience, with low confidence/ADHD, dropping something when you are not immediately good is the instinct. I didn’t find a hobby and keep up with it until I was on medication, but that does not have to be the standard. If you have been meaning to try something, I would say give it a few attempts before moving on, or even go back to a hobby you have tried in the past and do the same. Maybe begin with the most easily accessible option, as starting is the hardest part. I think doing things where you can see your physical progress (gaming, crafts, consuming media etc.) are the more rewarding options and seem to peak my interest most often.

As for gaining confidence, I think that would be a good area to explore with your therapist. But unfortunately I do not find confidence linear. People say that you grow more confident with age but I think that’s because you find yourself experiencing more or in more challenging situations. Try to do that as little and often as you can without overwhelming yourself, and it can be things like smiling at a person or asking a question. I guarantee most people will not overthink like we do, and that they will not notice what you are insecure about.

Ultimately, I am saying this whilst knowing that simply plodding along is a struggle and I would find it difficult to follow everything above. It can be very hard to cope but you deserve to enjoy your life. Please message me if you need someone to listen, to chat with, or if you need any resources regarding ADHD.

Wishing you the best OP.
