How to stay positive during my last year?

Hey everyone! My name is Daniel and I attend college in Texas, going to be a senior in the upcoming fall.

The last year has been pretty rough mostly since I’m a transfer student from a previous university and I found it harder to find a social life as a transfer.

I’m majoring in math, GPA is around 2.8, which concerns me since most actuarial jobs require a 3.0 or higher and the math courses I’ve been taking are as hard as hell.

My second option after graduating would be to join the navy as an officer, which sounds more realistic as they pay more attention to test scores than the GPA.

My major concern is my frustration with dating. I’m 22 and never had a gf before. I struggle with a mild form of autism which makes natural socializing very difficult. The way I’m trying to work on that is working out this summer A LOT. I found that women in the past used to show me interest when I wasn’t fat, but back then my social skills were much worse since I couldn’t tell whether they liked me or not.

Tl;dr I’m going through the stress of graduating and finding a gf. Any advice would be appreciated. Thanks!
