Where is my head at?

My husband and I just had a baby almost 4 months ago. And I don’t feel like myself anymore. I’m less confident, I’m losing my hair, the baby weight is so hard to drop and my husband doesn’t want me touching him. It’s so much happening at once I’m not sure how to deal. I want to feel how did before my son. I want to be spontaneous and love on my husband. Idk where to begin on getting back on track and I just want to know if any other moms have felt like this and what did they do to feel better?
