Words of encouragement ??

Hello ladies. I have a 16 month old boy and he is my whole world. I love him with all my heart and same for my SO. They are my most favorite people! Anyways, I’m just here looking for some words of encouragement. Lately I’ve been having moments where I’m happy, I feel like I can get everything done and taken care of and love when I feel this way. But most times I’ve been feeling down, very tired, just wishing I could keep to myself for a week or so… I just straight up feel depressed. I know stress has a lot to do with it but damn. Sometimes I just feel like I can’t do it anymore. How do y’all push though this? I know I’m not the only one. I’ve been feeling like I should see a therapist but we literally can’t afford anything extra right now as we’re on a tight budget until my SO gets promoted at his job. Idk ladies. Anything will help. Thank you.
