Since Linda started taking

[Bassim]

I am wondering if my sentences sound natural. Would you please correct my mistakes?

Since Linda started taking a new sort of antidepressants, she suffers from extreme mood swings. One minute she can be chatty and laughing, and another, silent like a tomb.

Try this: Linda has been suffering from extreme mood swings since she started taking a new antidepressant. One minute she can be chatting and laughing; the next, she's as silent as a tomb.

Re-ordering the first sentence and removing the comma makes it more direct.
