11 week old crying does it get better?

Nikole
I'm a first-time mom I have an 11 week old and she cries a lot pretty much when not asleep or eating. Possible early teething. Nothing soothes her and my husband has to stay with her all day to be calm cyz i can't handle it. I just cry cuz nothing helps her I feel like a failure of a mom and feel bad that my hubby is stronger and more patient than me and she cries really hard almost as if she's in pain. I've tried gripe water or gas drops Tylenol everything. We recently switched her from Similac total Comfort to Gerber Soothe and haven't seen a difference in 3 days the only difference is she poops when you more about 4 times a day. She's on meds for reflux but she just seems miserable. Will it get better after 3 months is this normal? I'm desperate.
