It is okay not be be okay. Never ever be embarrassed about reaching out and well done for posting.
I've suffered with my Mental Health over the years, hell I don't know anyone that hasn't tbh, and it is definitely a rollercoaster - some days I feel genuinely light and happy and carefree, other days I don't want to get out of bed and I want everything and everyone to go away (but I can't stay in bed, because I have to get up and parent)
So..firstly...SELF CARE.
What do you do for you??
This has been the shittiest year for many people. Be kind to yourself, you have made it this far and it will get better from now onwards, people can start to mix socially again and the isolation will ease, I promise.
Does your DH know how youre feeling? If not, it's worth having a good chat with him. Is he generally supportive?
Do you have friends or nearby support? It really does take a village to raise a child; we are not designed to do this alone. I found parenting young children the most relentless, isolating time of my life..They made me who I am today, but I honestly was not prepared for how lonely and challening it was some days - make sure you keep reaching out on forums such as this, it can help you feel less alone.
Anti-D's wise, I spent years on them and they absolutely have their place. I reached a point where I didn't want to be on them anymore and I took a more holistic approach to my mental health, but you can't do nothing. Clearly you recognise that you aren't feeling well, so you need to do something...maybe counselling? A weekly massage/facial? Coffee with a friend etc?
It will pass, I promise.
