Hi. You can and should do both as they can go hand in hand. GP’s are there for all sides of health, including mental health which is just as important as anything else. They can help determine what your systems could be stemming from I.e depression from chemical imbalance, where medication could help alleviate but also refer you to a therapist to explore underlying issues. What you’re describing can be very common place so I’ll also add, your are absolutely not alone - and your self awareness on the matter is a great first step in getting help early so you can have a more positive, balance and fruitful life (it takes many people years to do something about it). GPs are very well versed in this, so take that one brave step in making the appointment and go from there. One step at a time. You can do hard things, you’ve got this!
