Weird breathing issue?

i have a feeling this could be depression/anxiety related. But over the past few days it’s been more often that I randomly find myself feeling short of breath. Often paired with lightheadedness, and this  kind of heaviness in my limbs. 

Its mostly annoying at this point, but when I am trying to get to sleep I will get to this point where I feel like I really have to focus on each breath and if I get distracted I just stop breathing. 

I am am thinking of making a doctors appointment but if it’s just weird random anxiety attacks I don’t want to waste their time.

Do you get palpitations? Any chest pains?

You won't be wasting their time even if it is anxiety they may be able to help good luck I know this must be scary
