Hi Jake here are the corrections:

The rain has already started.

I have to bring my unbrella wherever I go.

The days I do not exercise, my condition is not good.
Exercise makes me feel great.

I hope is does not rain tommorrow so I can go wakeboarding.
I will pray and ask God to stop the rain.
I hope to avoid rain during weekend.
I don't care whether it's raining or not because I will just stay at the office.

I feel sorry for him because his wife had an abortion.
Fortunately, his wife is good, so they can open wedding march.
I think their state of mind may not be healhy.

If I have my selfie stick, I don't need to ask someone to take our pictures.
I take a lot of pictures during summer vacation.
I put the best shot in the frame.
And then, I put the frame on my desk.
Although my work is stressful,  I'm ok when I see my family picture in the frame on my desk.

Wedding march is only one day for thier lives.

 A brand new smartphone is enough to take good pictures.
