Wethear ChangeLiving in Summer vs Winter

You've mentioned two distinct seasons, so I wanted to make your title more specific to what you've written in the text.

Always with change the climatI hate it when the weather changes because my rhinitis attacks, I hate it.

Before, I thought I preferred winter ato summer because where i live the summer is really hotit's hot in the summer where I live, and I hate sweating.

The winter it also has its negative sides, the coldsuch as walking up to the mud from the raincold.

Now, I've come to the conclusion that in the end I don't know which climateseason I prefer.

Just spelling

Always with the change the climateing of the seasons my rhinitis attacks, I hate it.¶

Climate implies a long term weather pattern for the area that goes beyond seasonal or weather changes.
You could refer to this as either 'the season/seasons' or 'the weather'.
I changed 'change' to a present continuous form since this is something ongoing/consistent that will likely happen in the future too.

Not technically a correction but we would call this 'seasonal allergies' instead of 'rhinitis' in general conversation!

Before, I thought I preferred winter aover summer because where iI live the summer is really hot and I hate sweating.

'I' is always capitalized in writing.

The wWinter it also has its negative sides, the coldsuch as waking up toin the cold and the mud from the rain.

Article for 'winter' isn't necessary, we usually use an article before a season if we're referring to a specific season as a point in time as in 'the summer of 1945'. If we're talking about the season in general then no article is needed. I capitalized it here since it's now the start of the sentence.

Just a slight phrasing movement in the second half of the sentence. If you're giving examples to support an idea you'll want to use a phrase just before your examples, something like 'for example', 'such as' or 'like' are common especially in spoken English.
The sentence reads easier with 'and' as the preposition when paired with 'such as', but you could use 'or' as well.

Now I've come to the conclusion that, in the end, I don't know which climateseason I prefer.
