I've had anxiety for pretty much my whole life and it's gotten worse since I started post secondary education. I've ended up dropping courses and developed depression too battling my anxiety symptoms and being exhausted from it, and now I'm feeling frustrated with myself for not being able to graduate on time.
I've been going to therapy for a little over 3 years now. My therapist is amazing and it's been really helpful. But my doctor suggested that I try medication now alongside that. I'm really scared of SSRIs because of everything I've read in my psych classes so my doctor said I can start with 25mg of Sertraline (Zoloft) to try out, which I can stop whenever I want if I don't like it.
I'm scared to start it because of some of the side effects (weight gain, decreased sex drive, etc.), I'm scared of developing a dependency, and skeptical about how much it'll help. I would really like to improve my motivation and energy because I feel tired all day from just being in my head, and can't get anything done some days. 

I would love some advice about starting 25mg of Zoloft and if anyone's comfortable, their experience with it.

TLDR: Not sure whether to start taking 25mg of Zoloft for my anxiety because I'm scared of side effects and dependency. Looking for advice and possibly other people's experiences with Zoloft.
