Could you explain my mistakes? Thanks a lot

Hello!
How are you doing there? How is the weather? It is a bit chilly and wet where I am. I am doing not bad.
I came home an hour ago and picked up my daughter from the kindergarten.
Unfortunately, I could not get my computer fixed.
I hope to buy a new one next month when I will get my salary.
Today I am going to the social service to deal with my mum' problems. I hope I will be able to deal with her problems.
I must go now.
Take care.

Corrections in order as they appear:

1. I don't think there is ncessary in this case. I think asking how I am is enough.

2. The sentence was restructed to explain that it it chilly and wet.

3. "the" is not needed, but it may be good to add "kindergarten class".

4. "will" is not needed again.

4. I don't think social needs to be capitalized.
