So, you are a freshmen and doubt upon your confidence. Huh, the fact itself is a real good sign. If in doubt, don't go! I cannot count how many times I was eager to fly, prepared the aircraft, got it out of the hangar ... just to feel a point at which I simply pushed the plane back into the hangar to get wherever by car.
Fly if you feel comfortable, especially in the beginning. As other said, as a freshmen (btw: at how many hours in flight?) do not overstretch new things. I am not advising the road you took - staying in the area and at fields familiar! I always told students to extend their skills step by step, but -> stay frequent on gaining new insights and you won't get that from resting in your training area. My rule of thumbs was one new thing at latest after three to five flights, but only one new thing - a new aircraft OR a new field OR new weather conditions OR new border to cross.
There already must have been the point in your training when we all felt the lack of confidence (usually when you circle and circle and cannot never get the landing right). Remember that feeling and how you went past it. Apply the same now, just go on.
