Hello @ginger77
Welcome to FamilyHub and thank you for posting. Please feel free to carry on posting on here - it can be about anything, or can just be about you letting off a bit of steam.
Have you ever thought about volunteering? It can be a great way to meet new people and get out of the house. It doesn’t have to be a huge commitment, just a couple of hours a week. Just a thought 
@alanwpickup’s suggestion to get in touch with your local carers centre is a great idea. Where I live the local centre is very active and offers all sorts of meetings and activities.
Finally, are there any other parents dropping of at college where you take your daughter? I just wondered if any of them might be feeling the same way?
All the best
Sarah
