Is math my calling or am I just bad

I'm currently a U1 comp sci student and have only done Comp 206, 250, Math 240. Both my comp courses were my worse courses to date and my gpa took a HIT. I struggled really hard in Comp 206 and 250. Math 240 grade was fine and it was my favorite course this semester.

Is math actually my calling or should I stick it out. I'm kinda daunted by doing a whole degree of proofs (math degree and/or joint math and cs) and I was thinking of originally doing joint comp sci and bio. Cause bios cool.
