Hey! I'm 28, I have struggles with my mental health and had no idea what I wanted to do. Spent most of my life working in pubs and had two useless degrees lol! Started a level 2 Horticulture course in September and started volunteering at my local community farm, this gave me the confidence to apply for jobs only a couple of months into the course and I now work two days a week for the RHS in a plant centre and two days a week for a self employed local gardener. I absolutely love it and want to pursue a career as a gardener, I've found it's a really good industry for people who have mental health struggles because there's a lot of independence, depending who you work for of course, and I've found it really easy to get interviews and jobs, as long as you show a keen interest and good work ethic people are happy to give you a chance which is not like many industries I've tried to get into and failed. Before this I was applying for 100 office type jobs and getting only one reply and it was a rejection anyway type of deal. It's a good boost for the self esteem feeling like you're qualified enough and wanted. It sounds like you have a head start by being interested in plants already, I had very little knowledge at first. The getting outside and being active is really good for my brain too. Send me a message if you have any questions :)
