Depression is no joke to anyone who has experienced it.
Ultimately no-one can help you unless you truly want to get better and are willing to work on it yourself. So be honest with yourself (it looks like you've made a good start) about your situation and what you'd like to accomplish.
Reach out to your family/friends for support and seek professional help. At the very least, see a GP and ask for a referral to a specialist.
If you previously had any hobbies, consider starting them up again, or look into something new that interests you. Having a long-term goal that you work towards while working on yourself will be beneficial. Also try and work on smaller projects, things that you can complete in a day or two to start a positive feedback loop of commencing and completing, which may motivate you further.
Don't expect a quick-fix. This will take a long time if you are serious about it.
