How do you find your happy again?

Ever since I had a miscarriage I have been miserable. I have been cruel, unwilling to change my life, and drowning in a pit of misery. I do not like going to therapist because they have laughed at my overeating problem when I tell them about it; and when I talk to them about miscarriage they say think of all the things that you get to do without having to worry about a baby. More importantly have have lost my desire to be sexually active with my partner. I tell him it’s because he’s too attached to his new job.

I am so lost and I would like to know what has helped you.
