Can you correct these sentences please? I have been walking for a month and I am really feeling better and happier. I have been fighting with her since last Sunday, we haven't talked to each other for quite a long time since then. I have been planning to buy this equipment for 2 months and finally/ ultimately I am able to do it (now).

Can you correct these sentences please? After walking for a month, I truly feel better and happier. Fighting since last Sunday, we haven't spoken for a long time. After planning to buy this equipment for two months, I am finally able to do it. Try to use the Present and Past Continuous Word Patterns less (e.g. "am walking", "was walking", "have been walking", "had been walking"). They are cumbersome and usually unnecessary. The ideas they express are better conveyed by simply using the participles as adjectives, as I have done in my corrections.
