It is no wonder that things have caught up with you, the issues you have had to deal with are extremely distressing any one of which could have brought you to your knees. The fact that you carried on so long was remarkable. You need to allow yourself time to recover mentally and physically for your daughter, your mum and dad and ultimately your son.
This is the time to focus on you and your health and well being. Take the time you need you can call any time if you need to.
You have done so well and will do so again, there are people who care about you, whatever negative stuff is said about you in your struggles you are an important person to us.
